COMPOSITION, LAMINATED STRUCTURE, AND METHOD FOR PRODUCING LAMINATED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a composition with excellent adhesion to an adherend, e.g. plastic (especially polypropylene, etc.).

SOLUTION: The composition includes (A) a polymer (A-1) for which the melting peak is not substantially observed or a polymer (A-2) obtained by modifying the polymer (A-1) with α,β-unsaturated carboxylic acids, the polymer containing structural units derived from propylene and 1-butene and wherein the propylene-derived structural unit content is 70-99 mol% and the 1-butene-derived structural unit content is 1-30 mol% and (B) a polymer (B-1) for which the melting peak is observed or a polymer (B-2) obtained by modifying the polymer (B-1) with an α, β-unsaturated carboxylic acid, the polymer containing structural units derived from ethylene and propylene and wherein the ethylene-derived structural unit content is 5-20 mol% and the propylene-derived structural unit content is 80-95 mol%.
