摘要：
An olefin polymer composition is provided comprising
(A) 100 parts by weight of a homopolymer of 1-butene composed substantially of 1-butene units or a copolymer of 1-butene and another alpha-olefin containing at least 60 mole % of units derived from 1-butene, and
(B) 7 to 120 parts by weight of a homopolymer of propylene composed substantially of propylene units, a block copolymer of propylene and another alpha-olefin containing at least 50 mole % of units derived from propylene, or a random copolymer of propylene and another alpha-olefin containing at least 90 mole % of units derived from propylene, at least one of components (A) and (B) being partly modified with (D) an unsaturated carboxylic acid or its derivative and the composition not containing (C) a crystalline random copolymer of propylene and another alpha-olefin containing 50 to 87 mole % of units derived from propylene. A laminated structure comprising a substrate and a layer of a 1-butene polymer laminated thereto through an adhesive layer of the olefin polymer composition is also provided.
