Abstract
Poly(vinyl chloride) was dehydrochlorinated in alkali solution and then grafted with 2-hydroxyethyl methacrylate (HEMA) using benzoyl peroxide as an initiator under a nitrogen atmosphere. The solubility of PVC- g-HEMA has been successfully achieved through the addition of poly(HEMA). The curing of the mixture of PVC- g-HEMA and poly(HEMA) effected through a blocked diisocyanate was investigated. The investigation involved the synthesis of three kinds of blocked diisocyanates and the effects of the grafting percentage, curing time, curing temperature and catalyst. A desired flexible and golden color film can be obtained by controlling the quantity of the curing agent.
