摘　　要：采用VCl3-(i-Bu)3Al-TiCl4作催化剂,将异戊二烯加入丁二烯进行共聚,制备了反式异戊二烯-丁二烯共聚物,并对其加工流变性进行了研究。结果表明,用反式异戊二烯-丁二烯共聚物代替反式-1,4-聚异戊二烯与NR共混,其共混胶的非牛顿指数及门尼粘度值均下降,加工流变性能得到改善。Using VCl3-(i-Bu)3Al-TiCl4 as catalyst,the trans-1,4-butadiene-isoprene copolymer(TPBI) was prepared by adding butadiene to isoprene for polymerization,and the processing rhological property was studied.The results showed that blending NR with trans-1,4-isoprene-butadiene copolymer instead of trans-1,4-polyisoprene could decrease the non-Newtonian index and Mooney viscosity of the materials,so that the processing rheological properties were improved.
