摘要
聚烯烃材料如聚乙烯、聚丙烯、聚异丁烯、乙丙橡胶或丁基橡胶等,在国民经济和日常生活中发挥着重要作用.通过可控聚合反应可以实现制备高性能烯烃聚合物材料及不同微观结构、序列结构及拓扑结构的烯烃基高分子材料.本文综述了近年来通过乙烯/丙烯配位共聚制备乙丙共聚物及通过异丁烯正离子聚合制备聚异丁烯和丁基橡胶领域的研究进展,总结了在齐格勒-纳塔催化剂、茂金属催化剂及非茂单活性中心钒催化剂催化乙烯/丙烯共聚方面的进展,论述了异丁烯单体可控/活性正离子聚合新引发体系、可控/活性聚合反应调控、聚合新方法与新工艺,归纳了基于烯烃可控聚合的大分子工程.
Polyolefin materials, such as polyethylene, polypropylene, polyisobutene, ethylene-propylene rubber and isobutene rubber, play important roles in the industry and our daily life. Polyolefin materials with high performance,various microstructure, sequence distribution and topological structure could be prepared by controlled polymerization of olefin. We summarized the recent work on ethylene/propylene coordination copolymerization and isobutene cationic polymerization to prepare ethylene-propylene rubber, isobutene rubber and polyisobutene. The design and synthesis of Ziegler-Natta vanadium catalysts, half-titanocene catalysts and single-site vanadium catalyst and their application for ethylene/propylene copolymerization were introduced. The novel initiating system for the controlled/living cationic polymerizations, transformation of polymerization character, cationic polymerization in aqueous medium with high efficiency, cationic polymerization in rotating packed bed reactor were developed. The macromolecular engineering based on the controlled polymerization of olefin was also introduced.
