Thermoplastic elastomers having improved surface properties

A method for the preparation of an adhesive thermoplastic elastomer composition, comprising the steps of

• (A) preparing a composition comprising a thermoplastic elastomer comprising a thermoplastic polyolefin homopolymer or copolymer resin matrix having dispersed therein discrete particles of an olefinic rubber which has been at least partially cured by dynamic vulcanization, and optionally common additives, and
• (B) blending 100 parts by weight of the composition of (A) with about 3 to about 60 parts by weight of a modifier comprising a copolymer obtained by the condensation reaction of about 10 to about 90 weight percent of a functionalized polyolefin with about 90 to about 10 weight percent of a polyamide, based on the total weight of functionalized polyolefin and polyamide, at a temperature of about 20.degree. C. above the melting point of the polyamide,
• with the proviso that the polyolefin of the functionalized polyolefin of (B) is selected from the group consisting of polymers of ethylene, propylene, 1-butene, 1-hexene, 4-methyl-1-pentene, and copolymers of ethylene with one or more alpha-olefins, and the functionalized polyolefin contains no less than about 0.3 weight percent, based on the total weight of the functionalized polyolefin, of functional group forming monomers.
