STUDIES ON GRAFT COPOLYMERIZATION OF ACRYLIC ACID ONTO POLY(VINYL CHLORIDE) VIA IN-SITU CHLORINATING GRAFT COPOLYMERIZATION
关键字：STUDIES,GRAFT,COPOLYMERIZATION,ACRYLIC,ACID,ONTO,POLY,VINYL,CHLORIDE,VIA,SITU,CHLORINATING,GRAFT,COPOLYMERIZATION,
As poly(vinyl chloride)(PVC) were used as backbone molecules of graft copolymers，a graft reaction may be initiated by different ways such as cationic[1], radical[2], radiation[3] and recently atom transfer radical polymerization (ATRP)[4].
