Abstract:This paper reviewed the recent research progress in the grafting and crosslinking modification methods for poly(vinyl chloride) (PVC). The grafting modification methods included the grafting of groups containing C, N or S elements on carbon atom of PVC chains as well as other nucleophilic substitution methods. The crosslinking modification methods involved peroxide crosslinking, triazine compound crosslinking, diene compound crosslinking, silane crosslinking, and other chemical crosslinking methods. Finally, the development prospect of chemical modification for PVC was prospected.
Keywords:poly(vinyl chloride)  graft  nucleophilic substitution  chemical crosslinking  modification
