Abstract

PURPOSE: To obtain titled modified product, having exceedingly enhanced adhesion, by the reaction of a saponified ethylene-vinyl acetate copolymer in a fused state with N-methylol(meth)acrylamide, in the presence of a catalyst and in the absence of any solvent.
CONSTITUTION: In the reaction of (A) a saponified ethylene-vinyl acetate copolymer with (B) N-methylol(with)acrylamide in the presence of (C) a catalyst, a modified ethylene-vinyl acetate copolymer is obtained, by reacting (A) in a fused state and in the absence of any solvent. Here, (A) is preferably composed of 80W 99mol% of an ethylene unit, 0W18mol% of a vinyl acetate unit and 0.01W20mol% of a vinyl alcohol unit. (C) is an acid catalyst, selected from ammonium compounds, inorganic acids and sulfonic acid derivatives, 0.1W6mol%, based on (B), of which is preferably used. 5W200mol%, based on the hydroxyl group in (A), of (B) is used.
