Title:
COMPOSITION, LAMINATED STRUCTURE, AND LAMINATED STRUCTURE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/005080
Kind Code:
A1
Abstract:
Disclosed is a composition with excellent adhesion to an adherend, e.g., plastic (especially polypropylene etc.). Said composition contains (A) and (B), as follows: (A): A polymer (A-1) for which the melting peak is substantially not observed or a polymer (A-2) obtained by modifying said polymer (A-1) with an α,β-unsaturated carboxylic acid, 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%. (B): A polymer (B-1) for which the melting peak is observed or a polymer (B-2) obtained by modifying said 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%.
