PVC氯化接枝聚合制备CPVC-g-VDF接枝共聚物的研究

Study on Preparation of Graft Copolymer CPVC-g-VDF by Chlorinated Graft Copolymerization of PVC

通过将聚氯乙烯(PVC)氯化原位接枝共聚含氟单体生成氯化聚氯乙烯接枝偏氟乙烯(CPVC-g-VDF),当配比为VDF占CPVC-g-VDF量的4%时,接枝聚合的效果最好,所得接枝聚合物的综合性能优于聚氯乙烯。

A graft eopolymer CPVC-g-VDF was prepared by PVC and vinylidiene flworide（VDF） chlorina- tion graft copolymerizated in situ. When the ratio of VDF to graft copolymer is 4%, the graft eopolymer got in copolymerization have better comprehesive properties than ones of PVC.
