Abstract
The present invention relates to a coupling type polymer and a preparation method thereof. The coupling type polymer is obtained by the reaction of a polymer of which the active terminal group is an alkali metal polymer and a coupling agent with a following chemical formula R1CH2OR2CH2OR3, wherein the R1 and the R3 are respectively aliphatic alkyl and alkenyl or a hydrogen atom, and the R2 is alkylene, alkenylene, bivalence ring alkyl, bivalent aryl radical or ether group with one or more than one oxygen atoms or C1-17 divalent radical of ketone group. The coupling agent has high coupling efficiency, and simultaneously, the coupling agent can not generate the harmful substance to make a pipeline corroded. Moreover, the coupling number of the obtained coupling polymer is lower than 3 so that the coupling polymer not only has good rubber mechanical physical property, but also has high transparency. Furthermore, the coupling polymer has good attrition resistance.
Description
The present invention relates to a kind of coupling type polymer and preparation method thereof, be specially the reactive terminal base and be alkali-metal polymkeric substance and get with novel coupler coupling.
Industrially often make initiator with organic alkali metal compound, polymerized conjugated diene or conjugated diolefine and monovinyl aromatic hydrocarbon monomer contain the carbonyl ion of active anion and the alkalimetal ion of cation to form the polymer ends base.And then utilize this base polymer of coupler coupling to form the multipolymer of linearity or hub-and-spoke configuration.The coupling center of coupler just becomes the core (nucleus) of this base polymer.This type of polymerization has more efficient more than the similar and different monomer polymerization method of contiguous segmentation (promptly not adopting coupling manner), operate more stable, thereby be used in the styrene butadiene rubbers of polybutadiene rubber, solution polymerization process and thermoplastic elastomer (as styrene-butadiene-styrene SBS by industry member widely, and styrene-isoprene-phenylethene SIS, styrene-ethylene/butylene-styrene SEBS, styrene-ethylene/propylene-styrene SEPS) manufacturing of product such as.
All there is following shortcoming in employed in the past coupler: English Patent shows for No. 1014999 with two halogenated hydrocarbons and prepares ABCBA coupling segmented copolymer as coupler, is with coupler and multipolymer negatively charged ion AB
-Reaction and form.There is following problem in this type of coupler: has the by product alkali metal halide after the coupling and produces, and corroded pipeline and residue in the rubber easily with the antiaging agent reaction and make it produce the flavescence phenomenon not only, while synthetic polymkeric substance is also opaque.Adding this type of coupler is listed in poisonous chemical substance and must not use by multinational.
Carbonic acid gas, dithiocarbonic anhydride are used in English Patent 1103939 inventions, and the sulphur carbonoxide is made ABCBA coupling segmented copolymer.The coupling efficiency of this type of coupler is low; Carbonic acid gas is a gas, the concentration of ordinary dissolution in the wayward solution.And dithiocarbonic anhydride has sulfide side products and takes place after the coupling of sulphur carbonoxide.Not only can cause wastewater problem simultaneously by contaminated polymers.
United States Patent (USP) 3668279 inventions use maleic anhydride (maleic anhydride) or dimethyl terephthalic acid ester to make coupler.This compounds coupling rate is low, and coupling post polymerization solution is yellow, and can form by-product alcohols and be present in and reclaim in the solvent and poison the organic alkali metal initiator.
United States Patent (USP) 3244664,3692874,3880954, compounds such as 3725369 invention use silicon halogenide and silica, silicon nitrogen, silicon sulphur are made coupler, this type of coupler multiform becomes star-type polymer, coupling rate height, but can form by products such as alcohols, organic amine and thio-alcohol, they do not exist only in reclaims in the solvent and poisons the organic alkali metal initiator, can make polymkeric substance produce the stench of amine or thio-alcohol simultaneously.
United States Patent (USP) 4039633 inventions use 1,3,5-tricarboxylic acid three benzene halides are made coupler, the result can form a large amount of not coupling polymkeric substance and the indefinite coupling polymkeric substance of coupling number, coupling post polymerization thing is because of containing the easily flavescence of carboxylic-acid functional base, and contain a large amount of alkali halide metallic compounds, also perishable pipeline causes the product transparency not good.
Poly epoxy resin is used in United States Patent (USP) 3468972 inventions, polyisocyanate, and poly-imines, polyacetals, polyketone, poly-acid anhydrides, polyester, poly-halogenide is made coupler.The coupling number of this type of coupler is difficult to control, and its coupling number is the hub-and-spoke configuration more than 3, forms the mixture of the coupling post polymerization thing of different coupling numbers easily.And because of coupler molecular weight height, be difficult for the hydrocarbon cosolvent dissolving, the terminal group of coupling simultaneously easily causes the easy variable color of product if having these functional groups.And its coupling efficiency is usually less than 60%, and strong peculiar smell is easily arranged, and perhaps has byproducts such as alcohols, halogenide.
United States Patent (USP) 3281383 inventions use polymkeric substance such as styrene-acid anhydride copolymer, epoxidation liquid polybutadiene, polyisocyanate benzene to make coupler.The shortcoming of its generation is identical with the situation of United States Patent (USP) 3468972.
United States Patent (USP) 4107236 invention uses diester classes, silicon halide compound to make coupler, can produce alcohols and alkali halide metallic compound after the coupling, and the shortcoming of generation is identical with 3244664 and 3668279 situation.

Step 1 polyreaction usually occur in several minutes to 8 hours during in.More suitable polyreaction is carried out in during 30min to 4 hour.As for polymerization temperature, in 0 ℃～200 ℃ scope, more suitable scope is 40 ℃～130 ℃ usually.
Polyreaction ends, and will implement second step, i.e. coupled reaction.The polymeric reactive polymer is mixed with coupler.This step must add any material to stop polyreaction or just to implement before polymer molecular chain is removed alkali metal atom, therefore, the living polymerization mixture must be at water with mixing of coupler, acid, and this type of thing such as alcohols adds just to carry out before the reactive polymer that deactivates.
In polymerization process, paradigmatic system must keep the inclusion-free state, and impurity comprises water, oxygen, carbonic acid gas, acetylene compound, halogen compounds, alcohol, organic acid and mineral acid.And monovinyl aromatic hydrocarbon and conjugated diolefine also must be through purification process before entering reactive system.Whole purge process must be at nitrogen, and argon gas carries out under the situation that the helium sealing gland exists.
Method of the present invention, be with have coupler that good coupling renders a service come with the reactive terminal base be that alkali-metal polymkeric substance carries out coupled reaction.This coupler not only can not produce the chloride corrosion pipeline in coupling efficiency height and the coupling process, can not produce alcohols, acids yet and forms the poisonous substance of active anionic polymerization.The coupling number of coupling post polymerization thing is lower than 3, is higher than 3 obviously differently with the coupling number of general starlike coupler, not only has good rubber manufacturing machinery characteristic, the heigh clarity that also has known coupling type polymer and lacked.It is well a lot of that the wear resistant that simultaneously polymkeric substance of the present invention presented also is the polymkeric substance of hub-and-spoke configuration than tradition.
Below for several embodiment so that method of the present invention, feature and advantage to be described, but be not that scope of the present invention should be as the criterion with claims in order to restriction the present invention.
