The progress in the synthesis of graft copolymers via controlled/living cationic polymerization and by three different synthetic strategies of grafting from, grafting onto and macromonomer, is reviewed. The influence of the chemical structures of macroinitiator, branched chain, macromonomer, distribution of initiating sites and functional groups along macromolecular chains, the length of branches and Lewis acids on grafting polymerization is summerized. The characteristics of the above three synthetic strategies of grafting from, grafting onto and macromonomer is proposed. The microstructure, morphologies and surrounding response property in the specific environment of the graft copolymers are further elaborated. The potential application of the graft copolymers are also discussed.
