Title of the Invention OLEFIN POLYMER COMPOSITION AND LAMINATED STRUCTURE INCLUDING SAID COMPOSITION AS ADHESIVE LAYER Abstract of the Disclosure An olefin polymer composition 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, (B) 10 to 600 parts by weight of a homopolymer of propylene composed substantially of pro- pylene 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, and (C) 10 to 600 parts by weight of a crystalline random copolymer of propylene and another alpha-olefin containing 50 to 87 mole % of units derived from propylene, at least one of components (A), (B) and (C) being partly modified with (D) an unsaturated carboxylic acid or its derivative; and a laminated structure comprising a sub- strate and a layer of a 1-butene polymer laminated thereto through an adhesive layer of the olefin polymer com- position.
