METHOD FOR PRODUCING VINYL ALCOHOL POLYMER CONTAINING CYCLIC CARBONATE GROUP

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a vinyl alcohol polymer which maintains the original performances of the polymer and contains a cyclic carbonate group with rich reactivity in a molecule. SOLUTION: A copolymer of an unsaturated monomer containing a cyclic carbonate unit and an aliphatic vinyl ester is saponified with an acid catalyst.
