Building a bridge medicine and building a bridge Characteristic polymer

摘要

PROBLEM TO BE SOLVED: To provide a crosslinking agent whereby an uniform crosslinking can be generated in a polymer, the volatilization and the elution are little and which is useful to give high water resistance and heat resistance to vinyl alcohol polymer typified by PVA and EVOH.;SOLUTION: The agent comprises an epoxy acetal compound represented by the formula (1) [R₁ and R₂ are each a lower alkyl group or a 2-4C alkylene group together; R₃ is a direct bond or a 1-7C alkylene group].;COPYRIGHT: (C)2002,JPO
