Fill-in-the-blank: The dispersant used in the suspension polymerization of polyvinyl chloride is abbreviated as PVA; it is obtained through purely alkaline hydrolysis of polyvinyl acetate. It is the only polymer that is not formed by the polymerization of monomers. Since some ester groups remain due to incomplete hydrolysis, the amount of hydroxyl groups after hydrolysis is referred to as ________. Answer: Polyvinyl alcohol ； Alcoholysis degree
