Abstract:
A composition comprising (A), (B), and (C). (A): A polymer (A-1) containing a structural unit derived from propylene and a structural unit derived from 1-butene, said polymer having a propylene-derived structural unit content ratio of 70-99mol% relative to all of the structural units in the polymer and a 1-butene-derived structural unit content ratio of 1-30mol% relative to all of the structural units in the polymer, and having a melting peak which is not substantially observed, or a polymer (A-2) obtained by graft polymerising an α, β-unsaturated carboxylic acid compound with polymer (A-1). (B): A polymer (B-1) containing a structural unit derived from ethylene and a structural unit derived from propylene, said polymer having an ethylene-derived structural unit content ratio of 5-20mol% relative to all of the structural units in the polymer and a propylene-derived structural unit content ratio of 80-95mol% relative to all of the structural units in the polymer, and having a melting peak which is observed, or a polymer (B-2) obtained by graft polymerising an α, β-unsaturated carboxylic acid compound with polymer (B-1). (C): A polymer (C-1) containing a structural unit derived from propylene and a structural unit derived from 1-butene, said polymer having a propylene-derived structural unit content ratio of 60-90mol% relative to all of the structural units in the polymer and a 1-butene-derived structural unit content ratio of 10-40mol% relative to all of the structural units in the polymer, and having a melting peak which is observed, or a polymer (C-2) obtained by graft polymerising an α, β-unsaturated carboxylic acid compound with polymer (C-1).
