活性自由基聚合研究的新动态──可逆加成-断裂链转移自由基聚合

New trend of living radical polymerization Reversible addition-fragmentation chain transfer radical polymerization

介绍了基于可逆链转移思想的“活性”／控制自由基聚合。着重介绍澳大利亚Ｒｉｚｚａｒｄｏ研究小组的最新研究成果：以双硫酯类化合物为链转移剂的可逆加成－断裂链转移自由基聚合。分析其活性特征。

A type of living radical polymerization based on reversible chain transfer,especially,reversible addition-fragmentation chain transfer (RAFT)radical polymerization using dithioester compounds as chain transfer agents developed by Rizzardo and his coworkers lately was reviewed with 25 references.The living characteristics and mechanism of this process were stated succinctly.Detailed comparisons were made with other living radical polymerization systems,such as ATRP,TEMPO etc.
