Propylene polymer composition.

Abstract

A propylene polymer composition is disclosed which comprises: (a) a crystalline propylene polymer having a melt-flow index of from 0.01 to 100 g/10 min.;(b) a first ethylene copolymer comprising ethylene and from about 3.0 to 50% by weight of at least one copolymeriz­able monomer selected from a vinyl ester and an unsaturated carboxylic acid ester; and at least one of(c) a first modified propylene polymer produced by reacting 100 parts by weight of a propylene polymer with from about 0.01 to 10 parts by weight of an organic unsatu­rated compound having at least one hydroxyl group and from about 0.01 to 10 parts by weight of an organic peroxide, and(d) a second ethylene copolymer comprising ethylene and at least one copolymerizable ethylenically unsaturated monomer having at least one epoxy group. The composition has excellent adhesion to two-compo­nent system polychloroprene type adhesives and two-component system chlorinated polypropylene adhesives.
