摘要: 首先介绍了可逆加成-断裂链转移聚合(RAFT)的聚合机理及其常用的RAFT试剂,并与其它两种活性可控自由基聚合[氮氧化合物媒介的自由基聚合(NMP)和原子转移自由基聚合(ATRP)]进行了简单的优缺点对比。其次,介绍了近些年在基于RAFT聚合制备功能化聚烯烃嵌段聚合物研究中取得的进展,重点综述了制备功能化聚烯烃嵌段聚合物时所采用的6种方法,包括①烯烃配位聚合与RAFT聚合相结合;②阴离子聚合与RAFT聚合相结合;③阳离子聚合与RAFT聚合相结合;④Click反应与RAFT聚合相结合;⑤开环聚合与RAFT聚合相结合;⑥叶立德活性聚合与RAFT聚合相结合。最后,对基于RAFT聚合策略设计合成功能化聚烯烃嵌段聚合物的研究前景与实际应用进行了展望。

Abstract: The paper briefly describes the general polymerization mechanism of reversible addition-fragmentation chain transfer (RAFT) polymerization and some common RAFT agents. The RAFT polymerization is compared with other two kinds of active controlled radical polymerizations [nitrogen oxide mediated free radical polymerization (NMP) and atom transfer radical polymerization (ATRP)]. The recent progress of synthesis of functional polyolefin block copolymers on the basis of RAFT polymerization is reviewed. Six kinds of combined methodologies based on RAFT polymerization aiming at the synthesis of functional polyolefin block copolymers are introduced:① Combination of olefin coordination polymerization and RAFT polymerization,②Combination of living anionic polymerization and RAFT polymerization,③Combination of cationic polymerization and RAFT polymerization,④Combination of Click chemistry and RAFT polymerization,⑤Combination of ring-opening polymerization and RAFT polymerization,⑥Combination of living polymerization of Ylides and RAFT polymerization. Finally,the prospect of the design and synthesis of functional polyolefin block copolymers via the strategy based on RAFT polymerization is presented.

Key words: reversible addition-fragmentation chain transfer polymerization (RAFT), functional polyolefin, block copolymers
