[0064] Experimental Example of Synthesis of Modified Conjugated Diene-Vinyl Aromatic Copolymer

[0065] First, 800 g of cyclohexane was added into the reaction tank as a solvent, and the temperature of the reaction system was maintained at 45°C. Next, 0.3 parts by weight (0.64 g) of 2,2-bis(2-tetrahydrofuryl)propane (2,2-di(2-tetrahydrofuryl)propane, DTHFP) was added into the reaction tank as a microstructure regulator. Then, add about 0.05 parts by weight of divinylbenzene (DVB) and stir for 10 minutes, then add 0.1 to 0.2 parts by weight of n-butyllithium (n-butyllithium) into the reaction tank to initiate polymer polymerization. agent, and produces a divergent star structure with divinylbenzene. Here, the molar ratio of the microstructure modifier to n-butyllithium is substantially about 2:1.

[0066] Next, take 44.7 grams of styrene (styrene) as the first monomer, and 168.3 grams of butadiene (butadiene) as the second monomer into the reaction tank to carry out polymer p...

Abstract

The present invention relates to a polysiloxane compound, a modified conjugated diene-vinyl aromatic hydrocarbon copolymer and a production method thereof. A polysiloxane compound has a structure of formula 1, and formula 1F1, F2, F3 and F4 are respectively selected from different groups and selected from the first group, the second group, the third group and the fourth group either. The first group is selected from C2-C10 hydrocarbon groups containing amino groups, C2-C10 hydrocarbon groups containing epoxy groups, C2-C10 hydrocarbon groups containing carbonyl groups, and C2-C10 hydrocarbon groups containing alkoxy groups. The second group is selected from C2-C10 hydrocarbon groups containing amino groups. The third group is selected from C2-C10 hydrocarbon groups containing epoxy groups, C2-C10 hydrocarbon groups containing carbonyl groups, C2-C10 hydrocarbon groups containing SiCl groups or C2-C10 hydrocarbon groups containing OR groups, and R is an alkyl group. The fourth group is selected from a C2-C10 hydrocarbon group containing an aromatic group or a C2-C10 hydrocarbon group containing an OR group, and R is an alkyl group. n is 1 to 60, m is 1 to 60, X is 1 to 60, Y is 1 to 60, and Z is 0 to 300. The molar ratio of the first group: the second group: the third group: the fourth group is 1-40:1-30:0.5-10:45-90.

Description

technical field [0001] The invention relates to a polysiloxane compound, a modified conjugated diene-vinyl aromatic hydrocarbon copolymer and a manufacturing method thereof. Background technique [0002] In general, conjugated diene-vinyl aromatic copolymers can be used to make tires. In order to save energy, people require tires to have lower rolling resistance to save fuel consumption. For the consideration of driving safety, people require tires to have excellent wet skid resistance. [0003] Usually, carbon black is added to the conjugated diene-vinyl aromatic copolymer to increase the hardness, tensile strength, wear resistance and tear resistance of the tire, so the addition of carbon black is mainly used as a base for various rubbers. Reinforcing agent. In addition, the addition of silica (Silica) to the tire can reduce the high temperature generated by the tire during rolling through the special cooling effect of silica, thereby reducing the consumption of kinetic...
