## Abstract

A polymer composition is herein disclosed, which consists essentially of: (A) 90 to 50 wt % of a saturated polymer having in one molecule (1) at least two groups of at least one type selected from the group consisting of an epoxy group of the formula ##STR1## (R is hydrogen or methyl), an alcoholic or phenolic hydroxyl group and an alkoxymethyl-substituted acid amide group of the formula ##STR2## (R is an alkyl group of C.sub.1 to C.sub.4) and (2) a repeating unit made of a nonaromatic methylene group or methine group; and (B) 50 to 10 wt % of a nonfunctional radical polymerizable monomer mixture consisting of (a) a radical polymerizable monomer having in one molecule at least one functional group selected from the group consisting of a carboxyl group, an acid anhydride group, an alcoholic hydroxyl group, an alkoxymethyl-substituted acid amide group of the formula ##STR3## (R is an alkyl group of C.sub.1 to C.sub.4) and an amino group of the formula --NR.sub.1 R.sub.2 (R.sub.1 and R.sub.2 are each an alkyl group of C.sub.1 to C.sub.8) and an ethylenic double bond, and (b) a radical polymerizable monomer having one epoxy ring and one ethylenic double bond in one molecule.
