Studies on synthesis of graft copolymers with p-chloromethylstyrene copolymers as macroinitiators

A series of graft copolymers were synthesized by ATRP initiated with macroi nitiators which had been made from copolymerization of p-chloromethylstyren e and other monomers, such as methyl methacrylate, butyl methacrylate, acry lonitrile, styrene, vinyl acetate, isobutene-maleic anhydride, styrene-male ic anhydride etc.. The graft copolymers were characterized by IR and H-1 NM R spectra. The numbers of graft points or the branches on the graft copolym ers were determined by Ion Chromatography. The design for the various struc tures and architectures of the graft copolymers was made by changing the co mpositions of the backbones and the branches. The results indicated that it is a versatile route to synthesize a lot of graft copolymers and will be c ommercially important in the future.
