摘要
聚烯烃是世界上产量和消费量最高的合成高分子材料,用途广泛,其多嵌段共聚物更具有特殊的性能。基于聚烯烃的多嵌段共聚物近年来所受到广泛关注,文中将从合成方法角度出发,系统综述基于聚烯烃的多嵌段共聚物的制备方法,重点介绍采用活性配位聚合、链穿梭聚合、烯烃复分解反应以及基于链行走机理的烯烃配位聚合合成嵌段数目大于3的聚烯烃基多嵌段共聚物的方法。
Polyolefins are the largest volume and consumption polymers in the world today and their applications are wide.Block copolymers usually display special properties due to their special architectures.Polyolefin-based multi-block copolymers have attracted much attentions in recent years.The synthetic methods of polyolefin-based multi-block copolymers with more than 3 blocks were reviewed.Four synthetic methods were mainly introduced:living coordination polymerization,chain shuttling polymerization,olefin metathesis of polymers containing double bonds,olefin coordination polymerization based on chain-walking mechanism.
