【摘要】 与其它可控/活性自由基聚合相比,可逆加成-断裂链转移(RAFT)自由基聚合具有适用单体范围广、反应条件温和、不受聚合实施方法的限制等优点,因此成为目前高分子合成研究最为活跃的领域之一。通过它不但实现了广泛单体的可控/活性聚合,还合成了嵌段、接枝、梳型、星型、无规及梯度等结构的聚合物。本文综述了RAFT自由基共聚合领域的研究进展,内容主要包括已报道的RAFT自由基共聚合反应体系和RAFT过程对共聚产物组成的影响。更多还原

【Abstract】 Reversible addition-fragmentation chain transfer(RAFT) polymerization is one of the techniques employed to obtain living/controlled radical polymerization.Due to the compatibility with a wide range of monomers and reaction conditions,the RAFT process appears considerably more versatile than other living or controlled radical polymerization process.Therefore RAFT radical polymerization has been studied extensively.This review highlights the progress in RAFT radical copolymerization since its first report in 1998.It gives an account of the monomer pairs that have been copolymerized to date,and addresses the influence of the RAFT process on the copolymer composition.更多还原
