RAFT Polymerization of Thermosensitive Gradient Copolymers Based on N-Alkyl Acrylamide

GUAN Qun,CAO Ya,LIU Xu,FENG Xin-liang,KANG Jian (State Key Laboratory of Polymer Materials Engineering,Polymer Research Institute of Sichuan University,Chengdu 610065,China)  
A series of homopolymers and gradient copolymers based on N-isopropylacrylamide(IPA) and N,N-dimethylacrylamide(DMA),with desired structure and low molecular weight distributions(PDI1.18),were successfully prepared by reversible addition-fragmentation chain transfer(RAFT) polymerization by the use of DMP as the RAFT reagent,and AIBN as the initiator.The gradient composition structure is formed due to the different reaction rates of IPA and DMA.
