Abstract

Abstract A crosslinkable polymer composition comprising: (I) 1% to 99% by weight of at least one olefin copolymer selected from the group consisting of: (A) copolymers composed of (i) a-olefins, (ii) unsaturated dicarboxylic acid anhydrides, and (iii) at least one compound selected from the group consisting of unsaturated carboxylic acid esters, and vinyl esters; (B) copolymers at least composed of olefins and unsaturated monocarboxylic acids; (C) copolymers obtained by saponifying and neutralizing olefin copolymers at least composed of olefins and unsaturated carboxylic esters; and (D) copolymers at least composed of olefins and unsaturated dicarboxylic acids or the half esters thereof; and (II) 99% to 1% by weight of at least one olefin copolymer selected from the group consisting of: (A) copolymers at least composed of olefins and glycidyl alkyl (meth) acrylates; and (B) copolymers composed of (i) at least one a-olefin, (ii) at least one compound selected from unsaturated carboxylic acid esters and vinyl esters, and (iii) at least one compound having a hydroxyl group or primary or secondary amino group in the side chain. The resultant crosslinkable polymer composition has excellent molding and processing characteristics and can provide crosslinked products having excellent heat resistance and adhesion properties.
