Abstract:

Heteroarm star-shaped styrene-isoprene-butadiene rubber (SIBR) was prepared through a new multi-functional coulpling agent. The effect of structure and dosage of coulpling agent on polymerization process was investigated; The initial application of SIBR in tire was also studied. The prepared SIBR maintains the good physical and mechanical properties of SSBR, and has higher wet skid resistance and lower rolling resistance than SSBR. The whole result indicates that, as a new rubber, SIBR has important application prospects in high perfomance tyres.

Keywords: integral rubber, multi-functional coulpling agent, anionic polymerization.
