Chlorine-containing graft-polymers were prepared by chain-transfer graft copolymerization, mechanochemical graft copolymerization and chlorinated-graft copolymerization. Their synthesis, characterization, and properties were discussed in this thesis. The results show: that the effects of chlorine content of CPE, reactive time, initiator concentration and monomer concentration on the reaction are critical; that a new polymer is synthesized in making an appointment with properties, for example, excellent proc...
