摘要
烯烃配位链转移聚合是基于过渡金属单活性中心催化剂和链转移剂的烯烃聚合方法,作为一种调控聚烯烃分子结构和性能的有效途径,近来被学术界和工业界所广泛关注。本文论述了烯烃配位链转移聚合的基本化学原理,进而讲述了在配位链转移聚合的基础上衍生而出的可控/活性催化链增长反应和链穿梭聚合反应的原理。论述了乙烯、丙烯和相关长链α-烯烃的配位链转移均聚合和共聚合反应,以及链穿梭聚合在合成聚烯烃新型材料方面的一些应用。最后展望了链转移配位聚合的发展趋势和前景。
Coordinative chain transfer polymerization （CCTP） based on the single-site transition metal based catalyst and chain transfer agent is a kind of method for olefin polymerization. CCTP can be used for tuning the microstructure and architecture of polyolefin efficiently, and is paid attention to widely by the academic and industrial. The basic mechanism of CCTP was discussed, and then controlled/living catalyzed chain growth and chain shuttling polymerization （CSP） was also discussed due to the similar reaction mechanism. The coordinative chain transfer homopolymerizaiton and copolymerization of ethylene, propylene and long chain α-olefin were reviewed and discussed. The research and develop of novel polyolefin materials based CSP method were also reviewed and discussed. The perspective of CCTP was discussed in the end.
