201137015 六、發明說明： 【發明所屬之技術領域】 本發明係關於運用於光學薄膜及/或液晶應用領域之溴化苯乙烯聚合 物以及用以製備該等溴化笨乙稀聚合物的方法。本發明中，部分實施例能 - 夠達到改良一種或一種以上機械性質的效果。 【先前技術】 本發明第一圖說明了一簡化的液晶圖元裝置。傳統的液晶顯示器 (LCD)圖元包含介於成對透明電極層2〇〇、202之間的一雙折射液晶層 300，前述透明電極層可以是氧化銦錫，也就是俗稱的丨丁〇導電玻璃。該電 極層200、202已經過定位液晶分子的表面處理^舉例來說，在一扭轉向列 型相位裝置中，一第一電極層200可能包含與X軸平行的單向橫溝槽201， 而一第二電極層202可能包含與γ軸垂直的縱溝槽2〇3。該第一與第二電 極層介於與一第一極化層1〇〇成九十度垂直之一第二極化層1〇2之間。各 s玄極化層與其相鄰的電極層呈一直線排列，以使偏極光充分穿透該極化層 與電極層。一光源400，例如一背光，位於圖元的一側。通常液晶分子層 在該顯示裝置内呈一直線排列以便以90度旋轉偏極光，使偏極光佈滿該液 晶分子層。同樣地，當光線由光源自後方穿過該顯示裝置時，光線可見於 s亥顯示裝置的正面。但是當液晶層3〇〇通電後，液晶分子重新定位電場， 無法充分旋轉入·射的偏極光以使其遍佈於該第二極化層1〇2，致使光線受 到該第二極化層的阻擋；因此液晶體通電後的淨效應為實際上沒有任何光 線可穿越圖元。 201137015 由於液晶層具有雙折射特性，離_置的光線有兩種折射率，亦即 稱為「料常」辭行分量錢_為「尋常」㈣直分量，喊兩者之 間的差異則為雙折射率Δη (參見方程式一）。 可接受影像品質的弧度即為所謂的視角。重點是視角的大小與液晶層 的雙折射率直接相^尤其是當平行與垂直分量相等時，則視角接近一百 八十度。但是通常其中—個分量遠大於另—個；而差距越大，視角就越小， 譬如，液晶層可驗有相當大的平行分量，耻，此纖置的視角大幅受 限。光學補償薄膜能實現平行與垂直分量的平衡，因而縮小&的大小，增 大視角。 方程式-：Δη=η0·Γν=η丄，丨丨 光學補償薄膜在液晶應賴術領域相當普遍。但是，由於延遲量 (etardation (「)）不穩疋’業界人士大都認為聚笨乙稀是較差的材質選擇。 如方程式二中，延遲量（「）是材質厚度⑷以及雙折射率⑽下的產 物。k或多或何歸因於料乙職—般正常操作溫度顧内擁有相對較 大的光彈性係數所致。同樣地，聚苯乙稀报容易受到應力⑽㈣的影響。 再者’聚苯乙_延遲量是-種德強大的波長，但是聚笨乙刺对熱性 差。基於上述理由，通常不會用聚苯乙烯製作光學補償薄膜。 方程式二： Γ=Δη.ςΐ 漠化聚笨乙驗-種常見的化學物質，但是卻因為各種固有問題而一 直未曾被運驗光學補償雜技術。舉絲說’擁有各鮮醜化程度的 溴化聚苯乙烯產物通常不相容。你可在一溶劑中混合兩種不同代換率（DS) 的>臭化t本乙稀中發現這種不相容的現象。例如，在1 2·二氣乙烧中混合 201137015 -DS-1 (單漠化）以及DS = 2 (二漠化）的兩種樣本產物可能產生霧化的 溶液即使上述兩種樣本皆可單獨溶解於該溶劑中。若將霧化溶液運用於 光學薄膜上將會產生重大f摘’亦g卩其無法形成透_細。上述問題不 . I存在於混合兩化程度的產物，也發生於單-献程度的產物上。由 某些製程巾所製造㈣化物可能包含代鱗相差甚大的分子，_導致不 相容問題以及造成該產物不適用於光學補償薄膜用途。 此外，利用較高溫度的製程、較長的反應時間及/或較高的催化程度製 作的產物分子1太低’以致於無法產生漠化過程中聚合物降解產生充分的 完整薄膜。 本發明中包含能夠提供克服一項或多項先前技術之缺點的漠化聚苯乙

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to brominated styrene polymers for use in optical film and/or liquid crystal applications and to methods for preparing such brominated stupid polymers. In the present invention, some embodiments are capable of achieving the effect of improving one or more mechanical properties. [Prior Art] A first diagram of the present invention illustrates a simplified liquid crystal cell device. A conventional liquid crystal display (LCD) picture element includes a birefringent liquid crystal layer 300 between the pair of transparent electrode layers 2, 202. The transparent electrode layer may be indium tin oxide, which is commonly known as a conductive layer. glass. The electrode layer 200, 202 has been subjected to surface treatment of positioning liquid crystal molecules. For example, in a twisted nematic phase device, a first electrode layer 200 may include a unidirectional lateral groove 201 parallel to the X axis, and A second electrode layer 202 may comprise a vertical trench 2〇3 that is perpendicular to the gamma axis. The first and second electrode layers are interposed between a second polarization layer 1〇2 which is perpendicular to a first polarization layer 1 at ninety degrees. Each of the s-polarized layers is arranged in line with its adjacent electrode layer so that the polarized light sufficiently penetrates the polarized layer and the electrode layer. A light source 400, such as a backlight, is located on one side of the primitive. Usually, the liquid crystal molecular layers are arranged in a line in the display device to rotate the polarized light at 90 degrees to cause the polarized light to fill the liquid crystal molecular layer. Similarly, when light is passed from the rear through the display device, light is visible on the front side of the display device. However, when the liquid crystal layer 3 is energized, the liquid crystal molecules reposition the electric field, and the indirect polarized light cannot be sufficiently rotated to spread over the second polarized layer 1〇2, so that the light is received by the second polarized layer. Blocking; therefore, the net effect of the liquid crystal after power-on is that virtually no light can pass through the primitive. 201137015 Because the liquid crystal layer has birefringence characteristics, the light from the _ set has two kinds of refractive index, which is called "normal", and the vocabulary is _ _ "normal" (four) direct component, the difference between the two is double The refractive index Δη (see Equation 1). The curvature that can accept image quality is the so-called angle of view. The point is that the size of the viewing angle is directly related to the birefringence of the liquid crystal layer, especially when the parallel and vertical components are equal, and the viewing angle is close to one hundred and eighty degrees. But usually, the component is much larger than the other one; and the larger the difference, the smaller the viewing angle. For example, the liquid crystal layer can have a considerable parallel component, shame, and the viewing angle of the fiber is greatly limited. The optical compensation film achieves a balance between parallel and vertical components, thereby reducing the size of the & and increasing the viewing angle. The equation -: Δη = η0 · Γ ν = η 丄, 光学 Optical compensation film is quite common in the field of liquid crystal processing. However, due to the delay (etardation (")) is not stable, 'people in the industry think that polystyrene is a poor material choice. As in Equation 2, the delay amount (") is the material thickness (4) and the birefringence (10) The product, k or more or more, is attributed to the fact that the normal operating temperature has a relatively large photoelastic coefficient. Similarly, the polystyrene is susceptible to stress (10) (4). The styrene-ethyl _ retardation amount is a strong wavelength of the genus, but the polystyrene thorn has poor thermal properties. For the above reasons, the optical compensation film is usually not made of polystyrene. Equation 2: Γ=Δη.ςΐ Desertification B-test - a common chemical, but has not been subjected to optical compensation hybrid technology because of various inherent problems. It is said that 'the brominated polystyrene products with various degrees of ugly are usually incompatible. You can This incompatibility is found in a solvent mixed with two different substitution ratios (DS) > stinky t. For example, mixing 201137015 -DS-1 in 1 2 · Egas Single desertification) and DS = 2 (two desertification) The two sample products may produce an atomized solution. Even if the above two samples are separately soluble in the solvent, if the atomized solution is applied to the optical film, a significant f-sampling will be produced. The above problems are not. I exist in the product of mixed degree, also occurs in the product of single-degree. The manufacture of some process towels (4) may contain molecules with very different scales, resulting in incompatibility problems. And the product is not suitable for use in optical compensation film. In addition, the product molecule 1 produced by using a higher temperature process, a longer reaction time and/or a higher degree of catalysis is too low to be able to generate desertification. Polymer degradation produces a sufficiently intact film. The present invention encompasses desertified polystyrene embodiments that provide the ability to overcome one or more of the prior art disadvantages, and these embodiments are all suitable for use in optical compensation films. In the middle of the package 3 relating to an optical compensation film, the optical compensation film comprises a 4 isotropic polymer composition according to the molecular formula [(CH2C_n composition) The argon (penta) group in the formula contains stupid, naphthalene, f, 'phenanthrene or fluorene or more, and the argon group contains at least one filament substituent, and the polymer composition can be made - having a positive double An optically transparent film with a refractive index. Some of the cross-benefit and the fascinating scales are based on the benzene-compounding process, which consists of: the next step: making a close to weight percentage of styrene polymerization solution in a suitable organic solvent. The Lewis domain catalyst is added to the solution, and the route added to the solution is compared with the total mass of the phenethyl chelate.

Mixing the reaction mixture for about 5 to 12 minutes; adjusting the temperature of the reaction mixture to between 10 and 10 ° C; adding 0-8 to 1.6 equivalents of a brominating agent to the reaction mixture in 2 to 60 minutes while continuously The reaction mixture was stirred to finally isolate a fibrous powder reaction product. Some embodiments of the present invention relate to an improved liquid crystal display element, comprising: a first polarized layer having a front side and a back side; a first electrode having a front side and a back side, and a first polarization layer is located on the back side thereof; a second polarization layer having a front surface and a back surface; a second electrode having a front surface and a back surface, and the second polarization layer is located on the front surface thereof; a layer operatively disposed between the first and second electrodes; a backlight or a reflective element disposed behind the back of the first polarized layer; and the improvement is that an optical compensation film is operatively disposed on the first Between the second polarizing layers, the compensating film comprises one or more brominated polystyrene compositions and/or one or more brominated and deuterated polystyrene compositions. 201137015 • Persons skilled in the art should be able to understand the effects and advantages of the present invention by reading and understanding the specification. [Embodiment] In some embodiments of the present invention, the optical film of brominated polystyrene is formed by bromination processing according to a degree of bromination which can be sufficiently controlled. In contrast to the prior art, the styrene bromide polymerized composition produced by the process of the present invention is capable of forming a film having actual optical clarity and low color. This result is also found in certain compositions suitable for optical coating of various substrates. Moreover, in certain embodiments, those compositions may produce mechanical properties suitable for use in making individual films and/or monoliths. Benzene bromide group An embodiment of the invention relates to a process for preparing a brominated styrene polymer for an optical film; more specifically, in some embodiments, the process comprises: (1) In a suitable organic / granule I as a solution of a fine polymer, the weight ratio of 5~20%; (2) at room temperature or a temperature range of 1 〇 to io ° C, according to the styrene The total weight of the polymer solution is added to a Lewis acid catalyst of about 3 to 2% by weight; (3) The brominating agent is pressed in a temperature range of 1 to 6 在一 in a temperature range of 1 〇 to 1 ic. 8 to 1_6 equivalent amounts of the bromine/styrene monomer unit are added to the above-mentioned well-stirred reaction mixture to produce a reaction product, and (4) the final reaction product is obtained by a conventional method in the art to produce a fibrous form, A powder product which has low chroma and high solubility in organic solvents. In order to retain the performance of the catalyst, it is quite advantageous to carry out the above reaction under anhydrous conditions; or alternatively, the reaction side may be carried out under an inert gas atmosphere such as money gas and/or argon gas. In the experiment 201137015, a positive pressure can be applied to the inert gas so as to drive a gaseous by-product (for example, desertified nitrogen) to a vessel provided with an aqueous inorganic test capable of neutralizing the acid gas. In the present invention, the (tetra) styrene polymer may be any ethylene-based polymer having (iv) undergoing substitution reaction and combining with the desert group by an aromatic ring, as may include polystyrene bromide, polyethylene-based stupid Polystyrene, poly(ethylene onion), poly(ethylene phenate) or the like. In some solid blue towels, polystyrene is particularly advantageous. In some embodiments of the present invention, the preferred weight average molecular weight (Mw) of the polystyrene used in the evolution process is 200,000~500, _g/m〇|e', which is determined by gel permeation chromatography.

In the ρ divisional example, 5 to (7) minutes after the addition of the evolution agent, the human water or the inorganic water-based solution (for example, sodium hydroxide or hydroxide) can be effectively inhibited and reacted, so that the organic layer can be isolated. It is extracted and further utilized by the herbicide. VII · 丨 includes but is not limited to sodium sulphate or sulphate.

For example, we can filter the organic layer to remove solid impurities, and then pour it into the organic solvent according to 201137015. The temperature at which the precipitate is produced is in hot water. The resulting sediment is rinsed with methanol or water and then air dried to produce a suitably pure product. Alternatively, we can deposit the unprocessed organic layer in an alcohol (such as decyl alcohol and/or ethanol); in this step, the resulting precipitate is usually a gelatinous mass containing residual organic solvent, which needs to be The colloidal mass is placed in an organic solvent and redissolved for further purification. The aforementioned organic solvent may be Ν_nonol 2 pyrrolidone (ΝΜΡ), ’ Ν 曱 dimethyl decyl decylamine (DMF), and cyclopentanone.
