摘要

综述了原子转移自由基“活性”聚合研究的进展，包括采用的各种引发体系、聚合反应机理、动力学研究以及所合成的各种模型聚合物。通过原子转移自由基聚合可以方便地合成各种结构的模型聚合物，包括窄分布的均聚物、交替、无规和渐变共聚物、特殊链端的聚合物、嵌段和接枝共聚物等。

Abstract

This review article systemtically summarizes the important advances in atom transfer radical polymerization (ATRP)

including various initiating systems

mechanism

kinetic investigation and the model polymers synthesized by this method. Simple organic halides are used as initiators. This new technique empolys redox process with transition metals in which a halogen atom is transferred reversibly between transition metal and polymer chain end. A low stationary concentration of growing radicals is in a fast dynamic equilibrium with the dormant species

so bimo lecular termination is minimized. There 're two types of ATRP. One is catalyzed by CuX

the other is catalyzed by RuCl

(PPh)

. Generally

ATRP is useful for synthesizing various polymers with molecular weights of 10

to 10

and low dispersites. This technique has been used to polymerize many kinds of vinylmonmers; to prepare random

gradient

alternating

block and graft copolymers; and to synthesize macromolecules with various topologies(branched

hyperbranched and star polymers).
