抄録

This study is directed to the synthesis of a series of well-defined graft copolymers with the controlled lengths of both the backbone and graft chains by the ruthenium-catalyzed living radical polymerization. The backbone polymer was first synthesized by the ruthenium-catalyzed living radical random copolymerization of methyl methacrylate and 2- (trimethylsilyloxy) ethyl methacrylate followed by the in-situ transformation of the silyloxyl group into the ester with a C-Br bond, which resulted in efficient multifunctional macroinitiators for living radical graft copolymerization. The methodology led to the novel controlled architectural copolymers, A_xBA_x-type block-graft copolymers, which can function as new building blocks for controlled nanostructures based on microphase separation and is different from that of the conventional ABA triblock copolymers. A series of well-defined A_xBA_x-type block-graft copolymers consisting of soft middle segments (dodecyl methacrylate) and hard outer graft chains (styrene) were synthesized by the ruthenium-catalyzed block and graft polymerizations to exhibit characteristics of a thermoplastic elastomer.
