Abstract

A new method is proposed to study the process of controlled/living radical copolymerization as well as the structures of the products. Computer simulation has been carried out to produce this LRP or CRP propagation including the activation/deactivation process. The information about segment distribution was obtained for the first time. The results show that under a stationary condition, controlled/living copolymer's composition and sequence distribution are totally identical to those prepared from the conventional free radical copolymerization (FRcP). In other words, the activation/deactivation process of controlled/living radical copolymerization has no effect on copolymer's microcomposition and microsequence structure.

Amphiphilic block and statistical copolymers of vinyl ethers (VEs) with pendant glucose residues were synthesized by the living cationic polymerization of isobutyl VE (IBVE) and a VE carrying 1,2:5,6-di-O-isopropylidene-D-glucose (IpGlcVE), followed by deprotection. The block copolymer was prepared
