原子转移自由基聚合(ATRP)技术是合成结构规整性聚合物的有效途径。综述了近十年来采用ATRP技术合成多嵌段共聚物的研究进展。从引发剂、共聚单体和反应条件等方面讨论了ABA型、ABC型和ABCBA型等类型多嵌段共聚物的合成、性质与潜在应用。对原子转移自由基聚合技术在合成功能性多嵌段共聚物中的应用前景进行了展望。
Atom transfer radical polymerization (ATRP) is an effective route to synthesize polymers with welldefined structures. Multiblock copolymers synthesized by ATRP in recent ten years are reviewed. The syntheses, properties and potential applications of multiblock copolymers, such as ABA-type, ABC-type, and ABCBA-type, are discussed in terms of monomers, initiators, and polymerization condition. Application of ATRP technology to the synthesis of functional multiblock polymers is predicted.
