ABSTRACT:
A water-insoluble hydrophilic polymer composition capable of crosslinking at ambient temperature. The composition contains (A) a water-insoluble hydrophilic copolymer prepared by copolymerizing (a) at least one carboxyl group containing ethylenically unsaturated monomer selected from acrylic acid, methacrylic acid, maleic anhydride, fumaric acid, itaconic acid and citraconic acid, (b) at least one amino group containing ethylenically unsaturated monomer of the formula: ##STR1## where R.sub.1 -R.sub.4 are specifically defined, and (c) an ethylenically unsaturated monomer selected from (i) a monomer of the formula: ##STR2## (R.sub.6 being alkyl), (II) A MONOMER OF THE FORMULA: ##STR3## and (iii) diacetone acrylamide, and (B) a polyepoxide crosslinking agent having at least two terminal epoxy groups. The water absorption rate of the polymer can be adjusted over a wide range and has sufficient coating strength and bonding strength to withstand long periods of immersion in water.
