MODIFIED VINYL ALCOHOL-BASED POLYMER, MODIFIED VINYL ESTER-BASED POLYMER AND METHODS FOR PRODUCING THEM

摘要

PROBLEM TO BE SOLVED: To provide an amino group-containing modified vinyl alcohol-based polymer that has excellent water solubility and excellent reactivity with a crosslinking agent and gives a molded product such as film, etc., having excellent water resistance by reaction with a crosslinking agent.;SOLUTION: The modified vinyl alcohol-based polymer comprises a vinyl alcohol unit and a constituent unit represented by formula (I) (wherein R¹-R⁵ are each independently a hydrogen atom or 1-8 C group; A is a single bond, oxygen atom or 1-8 C divalent group).;COPYRIGHT: (C)2013,JPO&INPIT
