摘　　要：乙烯基共轭二烯烃聚合物由于具有大量乙烯基而展现出独特的性能,其中的1,2-聚丁二烯和3,4-聚异戊二烯及其共聚物具有优异的抗湿滑性能、低滚动阻力和低生热,在高性能绿色轮胎领域具有广阔的应用前景。铁系/钼系催化体系可以催化1,3-丁二烯和异戊二烯发生配位聚合制备1,2-聚丁二烯和3,4-聚异戊二烯及其共聚物;还可以使共轭二烯烃单体与极性单体共聚制备官能化改性产品,有效改善非极性聚合物与极性无机填料的相容性,使其应用于高性能绿色轮胎等领域。综述了近年来用于制备1,2-聚丁二烯和3,4-聚异戊二烯及其共聚物的铁系/钼系催化剂的研究进展和所制备聚合物的应用研究进展。Vinyl-conjugated diene polymer exhibits unique properties due to their abundance of vinyl.Among them,1,2-polybutadiene and 3,4-polyisoprene and their copolymers have excellent wet skid resistance,low rolling resistance,and low heat generation,which make them have broad application prospects in high-performance green tires.The iron based and molybdenum based catalysts can catalyze the coordination polymerization of 1,3-butadiene and isoprene to prepare 1,2-polybutadiene,3,4-polyisoprene and their copolymers.In addition,conjugated diene monomer and polar monomer can be copolymerized by these two catalysts to prepare functional modified products,which can effectively improve the compatibility of non-polar polymer and polar inorganic filler,so that they can be applied to high-performance green tires.In this paper,the research progresses of iron based and molybdenum based catalysts for preparation of 1,2-polybutadiene and 3,4-polyisoprene and their copolymers and the application of the prepared polymers in recent years are reviewed.
