A polyvinyl alcohol polymer which is obtained by saponifying a copolymer of a vinyl ester monomer and a polyfunctional monomer that contains two or more polymerizable unsaturated bonds in the molecule, and which is characterized in that: the average degree of polymerization of the polyvinyl alcohol polymer as measured by the method described in JIS K6726: 1994 is 3000-6000; the reaction rate of polymerizable unsaturated bonds in the polyfunctional monomer is 55-75%.
聚乙烯醇系聚合物，其特征在于，其是通过乙烯酯单体与分子内包含两个以上聚合性不饱和键的多官能性单体的共聚物的皂化而得到的聚乙烯醇系聚合物，聚乙烯醇系聚合物的利用JIS K6726:1994中记载的方法测定的平均聚合度为3000～6000，多官能性单体的聚合性不饱和键的反应率为55～75％。
