摘要
综述了阴离子聚合反应中微观结构调节剂的发展历史、分类和特点,介绍了它们在聚丁二烯橡胶、聚异戊二烯橡胶、溶聚丁苯橡胶(SSBR)和苯乙烯/异戊二烯/丁二烯三元集成橡胶(SIBR)中的应用,着重介绍了各种微观结构调节剂对橡胶聚合物链中的聚丁二烯的1,2-结构和聚异戊二烯的3,4-结构的调节能力,并指出了结构调节剂今后的主要发展方向,即调节体系由一元体系向二元体系发展,调节剂分子结构由对称向不对称发展。
This paper deals with various kinds of structure modifiers for regulating the microstructures in the area of anionic polymerization, their history, dassification,characteristic and applications in polybutadiene rubber, polyisoprene rubber, SSBR and SIBR. The influence of various kinds of structure modifiers on 1.2-PB structure and 3.4-PI structure in polymers, and the direction of primary development of modifiers are introduced. The development orientation of structure modifiers is from single system to duality system., the structure is from symmetrical to asymmetrical.
