Description

Verfahren zum Herstellen von klaren, hochwertigen Mischpolymerisaten auf der Grundlage siliciumorganischeT Verbindungen Gegenstand' ,der Erfindung ist ein Verfahren zum Herstellen vom; klaren, hochwertigen Mischpodymerisa,ten auf der Grundlage siliciumarganischer Verbindungen.Process for the production of clear, high-quality copolymers based on organosilicon compounds is the subject matter of the invention a method for producing; clear, high-quality mixed podymerisa, th on the Basis of organosilicon compounds.

Unter siliciumorganischen Verbindungen werden Verbindungen des Typus »Silicon« von der chemischen Struktur R-Si-O O H oder R1R. Si-O oder RA R3 Si- O H oder deren Kondensationsprodukte verstanden, wobei die einzelnen R gleiche oder verschiedene aliphatische, olefinische oder aromatische Reste sein können. Hochwertige optisch 'Aare Mischpolymerisate werden erhalten, wenn man erfindungsgemäß die siliciumorganischen Verbindungen mit ungesättigten Kohlenstoffverbindungen, wie Olefinen bzw. deren Derivaten, wie Halogenderivaten u. dgl., Olefincarbonsäuren oder Ester, wie z. B. Vinylverbindungen, z. B. Vinylchlo,r,i:d!, Acr'yls,äure, Ester der Methacrylsäure u..dg'l., aber auch ungesättigten Kohl.enistoffverbindungen mit mehr als einer Doppelbindung bzw. Dreifachbindümg, polymerisiert.Organosilicon compounds are compounds of the type "Silicon" with the chemical structure R-Si-O O H or R1R. Si-O or RA R3 Si-O H or their condensation products understood, where the individual R is the same or can be various aliphatic, olefinic or aromatic radicals. High quality optically 'Aare copolymers are obtained if, according to the invention, the organosilicon Compounds with unsaturated carbon compounds such as olefins or their Derivatives such as halogen derivatives and the like, olefin carboxylic acids or esters such as. B. Vinyl compounds, e.g. B. Vinylchlo, r, i: d !, Acr'yls, äure, ester of methacrylic acid etc., but also unsaturated carbon dioxide compounds with more than one double bond or triple binding, polymerized.

Beispielsweise wird ein. Methylsilicon: mit einem Siliciumgehalt von etwa 36% mit io bis; 90°/o Meth.acrylsäuremethylester polymerisiert. Zweckmäßig geht man dabei so vor, daß man in niedrigpolymere Silicone, die beispielsweise in Butanol gelöst sind, die ungesättigte Kohlenstoffverbtindfung einträgt und dann am Rückflußkühler mehrere Stunden kocht. Nach Abdampfung des Lösungsmittels verbleibt eine klare, dünn- bis; zähfüs,sige Masse, die gegebenenfalls. unter Zugabe eines die Polymerisation beschleunigenden Mittels, wie Benzoylperoxyd, Titantetrachloirid, Aluminium.chloiri:d, Zinntetrachlorid od. dgl., bei erhöhter Temperatur zu einer hartem bis glasig-harten Masse polymerisiert.For example, a. Methyl silicone: with a silicon content of about 36% with io bis; 90% methyl methacrylate polymerized. Appropriate goes it is done in such a way that one in low-polymer silicones, for example in butanol are dissolved, enters the unsaturated carbon compound and then on the reflux condenser cooks for several hours. After evaporation of the solvent, a clear, thin to; viscous, sige mass, which if necessary. with the addition of one the polymerization accelerating agent, such as benzoyl peroxide, titanium tetrachloiride, aluminum chloiri: d, Tin tetrachloride or the like, at elevated temperature to a hard to vitreous hardness The mass polymerizes.

Selbstverständlich können auch verschiedene siliciumorganische Verbindungen: in, Gemischen und ebenso, verschiedene Kohlenstofverb:indungen gleichzeitig benutzt werden, um die dem Verwendungszweck angepaßten Eigenschaften zu erzielen.Of course, various organosilicon compounds can also be used: in, mixtures and also, different carbon compounds used at the same time in order to achieve the properties adapted to the intended use.

Durch Verwendung geeigneter Reaktionspaare gelangt man zu klaren, harten Körpern, die sich durch große Temperaturbeständigkeit und außerordentliche chemische Resistenz auszeichnen. Sie lassen sich ähnlich wie Kunstharz mit den üblichen Mitteln bearbeiten.Using suitable reaction pairs leads to clear, hard bodies, which are characterized by great temperature resistance and extraordinary distinguish chemical resistance. They can be made similar to synthetic resin with the usual Edit funds.
