The copolymers were formed by the graft copolymerization of PVC with acrylic rare earth.The principle and method of the graft copolymerization of PVC and acrylic rare earth were discussed.The graft copolymers were characterized by FT-IR spectra and scanning electron microscope(SEM).The thermal stability of the graft-copolymers was studied by thermogravimetric analysis(TG).The experiment results show that the thermal resistance and toughness of the graft copolymers are obviously enhanced.
