ABSTRACT:
A polyvinyl alcohol graft terpolymer comprises 70-30% by weight of polyvinyl alcohol and 30-70% by weight of acrylate/maleic anhydride copolymer having 95-30 mole % of acrylate and 50-70 mole % of maleic anhydride, which is prepared by a condensation-coupling reaction through esterification being performed between the hydroxy groups of the polyvinyl alcohol and the anhydride groups of the acrylate/maleic anhydride copolymer. The polyvinyl alcohol graft terpolymer may be further subjected to a heat treatment to have better water resistance and mechanical properties due to the interchain ester linkage between the hydroxyl groups and the anhydride groups therein. Alternatively, the polyvinyl alcohol graft terpolymer may be reacted with an amine to produce a maleamic acid intermediate, and then dehydated to form a maleimide derivative.
