Title:
POLYVINYL ALCOHOL-BASED POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/238674
Kind Code:
A1
Abstract:
This polyvinyl alcohol-based polymer is obtained through saponification of a copolymer of a vinyl ester monomer and a trifunctional monomer, and is characterized in that the average degree of polymerization of the polyvinyl alcohol-based polymer as measured using a method described in JIS K 6726:1994 is 3000-6000, and the average reactive number of unsaturated sites of the trifunctional monomer is 1.7-2.3.
