Abstract

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 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, 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 substrate and a layer of a 1-butene polymer laminated thereto through an adhesive layer of the olefin polymer composition.

Claims



What is claimed is:
1. An olefin polymer composition comprising
(A) 100 parts by weight of a member of the group consisting of a homopolymer of 1-butene composed substantially of 1-butene units, and 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 member of the group cosisting of a homopolymer of propylene a block copolymer of propylene and an alpha-olefin having 4-8 carbon atoms and at least 50 mole % of units derived from propylene, and a random copolymer of propylene and an alpha-olefin having 4-8 carbon atoms and containing at least 90 mole % of units derived from propylene, and
(C) 10 to 600 parts by weight of a member of the group consisting of 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 modi...
