Abstract

The invention discloses a fluorinated styrene / butadiene copolymer and a preparation method thereof. The fluorinated styrene and butadiene copolymer is characterized in that: based on 100% of the total amount of the obtained copolymer, each The proportions of the components are as follows, the content of fluorostyrene in mass percent is 1% to 30%, and the content of butadiene in mass percent is 70% to 99%; the structure of butadiene in the polymer is 1,4-structure and 3, There are two forms of 4-structure, the content of 1,4-structure polybutadiene is 45%-98%, and the content of cis-1,4-polybutadiene is 30%-97%. The catalytic system of the preparation method uses a rare earth Sc compound as a catalyst, and a boron reagent as a cocatalyst, and the two together constitute a catalytic system for preparing fluorostyrene and butadiene copolymers. Under this catalytic system, fluorostyrene and butadiene Diene is polymerized to produce a copolymer of fluorostyrene and butadiene.

Description

Fluorinated styrene / butadiene copolymer and preparation method thereof technical field The invention belongs to the field of styrene-butadiene rubber, specifically relate to a class of fluorostyrene / butadiene copolymer and preparation thereof preparation method. Background technique Styrene-butadiene rubber based on styrene and butadiene has the advantages of wear resistance, aging resistance, heat resistance and fast vulcanization speed, and is Widely used in tire manufacturing industry. However, due to the lack of functional functional groups in the existing styrene-butadiene rubber, in the follow-up with carbon black and When silica is processed, the dispersion of carbon black and silica is poor, which affects the performance of tires. In order to make up for the defects of styrene-butadiene rubber, in The introduction of functional groups into styrene-butadiene rubber has become an effective way to solve this problem. Among various functional groups, Fluorin...
