PURPOSE:To provide the titled composition having excellent adhesive property, resistance to boiling water, mechanical strength, hardness, and solvent resistance and consisting of a modified ethylene/vinyl acetate copolymer, a low polymer prepared from maleic anhydride and a styrene, and an epoxy resin. CONSTITUTION:100pts.wt. of (A) a modified ethylene/vinyl acetate copolymer prepared by grafting an unsaturated carboxylic acid onto a hydrolyzed product of an ethylene/vinyl acetate/(unsaturated carboxylic acid)copolymer containing 3- 40mol% of vinyl acetate is compound with 1-40pts.wt. of (B) a low polymer prepared from maleic anhydride and a styrenic monomer of the formula (R1: H, 1-4C alkyl; X1 and X2: each H, alkyl, cycloakyl, aryl, aralkyl, and halogen), and 5-20pts.wt. of (C) an epoxy resin of m.p. 50-130 deg.C, mean MW 800-4,000, epoxy equivalent 400-3,000 and having two or more epoxy goup per molecule. |
