Reversible addition-fragmentation chain transfer(RAFT) free radical polymerization is a new controlled active free radical polymerization technique emerged recently.Due to its compatibility with a wide range of functional monomers and mild reaction conditions,RAFT technique can not only control polymer's relative molecular weight and its distribution,but also obtain functional polymer with well-defined structure,and has become an effective way of polymer molecular design.This paper reviews research progress of RAFT polymerization technique application in synthesizing well-defined polymers,such as star polymer,block polymer,comb shaped polymer,dendritic polymers,gradient copolymer,and so on.
