原子转移自由基聚合研究进展

摘要

原子转移自由基聚合(Atom transfer radical polymerization,ATRP)是一种发展较快的可控/活性聚合技术,现已广泛应用于聚合物分子结构设计及众多功能高分子材料的合成.本文在综述了ATRP的反应机理的基础上,介绍了引发剂、催化剂、配体、单体等对ATRP的影响,同时综述了降低(或去除)金属盐含量的绿色、高效ATRP聚合体系,如引发剂持续再生活化ATRP,电子转移生成(再生)活化剂ATRP,铁催化体系,光催化体系等.近年来发展的无金属光诱导的有机催化ATRP聚合体系也做了综述.%Atom transfer radical polymerization ( ATRP ) , as a new type of controllable/living polymer-ization reaction has been developed rapidly. This polymerization technology has been widely used in the molecular structure design of polymers and the synthesis of many functional polymer materials. In this paper, the basis of the reaction mechanism of ATRP is reviewed. The influence of initiator, catalyst, ligand, monomer on ATRP was introduced. The green and efficient reduction of metal salt content were reviewed, such as initiators for continuous activator regeneration ATRP, activators (re)generated by e-lectron transfer for ATRP, ATRP catalysted by iron compond, photo, etc. The highlight of recent de-velopment of metal free organic catalyzed ATRP polymerization system were also reviewed.
