Polyfunctional group integrated rubber and preparation method thereof

The invention discloses a polyfunctional group integrated rubber and a preparation method thereof, the polyfunctional group integrated rubber has the following structure: # imgabs0 #, in which R is alkyl or aryl with different carbon atom numbers; the SIBR is random copolymer rubber of three monomers of styrene, butadiene and isoprene, and the number-average molecular weight of the SIBR is 150000 to 400000. The multi-functional-group integrated rubber prepared by the invention has better mechanical properties, lower rolling resistance and good wet skid resistance, so that the multi-functional-group integrated rubber has better application prospects in high-performance tires. 本发明公开了一种多官能团集成橡胶及其制备方法，该多官能团集成橡胶具有以下结构：#imgabs0#其中，R为不同碳原子数的烷基或芳香基；SIBR为苯乙烯-丁二烯-异戊二烯三种单体的无规共聚橡胶，所述SIBR的数均分子量为150000-400000。本发明制得的多官能团集成橡胶具有更好的力学性能，较低的滚动阻力，良好的抗湿滑性能，因此在高性能轮胎中具有较好的应用前景。
