Composition, laminated structure and method for manufacturing laminated structure

Abstract

A composition can be provided with superior adhesiveness toward adherends, for example, made of plastic (in particular, polypropylene, and the like). The composition includes the following (A) and (B). (A): Polymer (A-1) having structural units derived from propylene and structural units derived from 1-butene, wherein the content of the structural units derived from propylene is 70-99 mol % based on all the structural units of Polymer (A-1), the content of the structural units derived from 1-butene is 1-30 mol % based on all the structural units of Polymer (A-1), and a melting peak is substantially not observed, or, Polymer (A-2) obtained by modification of Polymer (A-1) with an α,β-unsaturated carboxylic acid, (B): Polymer (B-1) having structural units derived from ethylene and structural units derived from propylene, wherein the content of the structural units derived from ethylene is 5-20 mol % based on all the structural units of Polymer (B-1), the content of the structural units derived from propylene is 80-95 mol % based on all the structural units of Polymer (B-1), and a melting peak is observed, or, Polymer (B-2) obtained by modification of Polymer (B-1) with an α,β-unsaturated carboxylic acid.
