The present invention relates to an adhesive thermoplastic elastomer composition comprising three major components as follows: (a) at least one polyolefin modified by a chemically reactive functional group such as a carboxylic acid or its derivatives including anhydride, acid chloride, isocyanate, oxazoline, epoxide, amine and hydroxide; (b) at least one other polymer prepared from one or more of the following: ethylene, propylene, butylene, isobutylene, octene-1, 4 methyl pentene-1, hexene-1 or mixtures; and (c) at least one olefinic elastomer, including elastomeric ethylene-propylene copolymers, elastomeric ethylene-propylene terpolymers, polyisoprene, polyisobutylene, ethylene-propylene copoloymer rubber, polybutadiene, natural rubber, elastomeric polyesters, polyurethane elastomers, polyamide elastomers and mixtures.

An adhesive thermoplastic elastomer composition consisting essentially of: (a) about 15 to 40 weight percent of at least one polyolefin selected from the group consisting of polyethylene, polypropylene and mixtures thereof, modified by grafting with an unsaturated an aliphatic carboxylic acid or its derivatives selected from the group consisting of acid anhydride, acid chloride, isocyanate, oxazoline, epoxide, amine and hydroxide; (b) about 10 to 70 weight percent of at least one other non-elastomeric polyolefin resin prepared from at least one monomer selected from the group consisting of: butene, isobutylene, octene-1, 4-methyl pentene-1, ethylene, propylene, hexene-1 or mixtures thereof; and (c) about 20 80 weight percent of at least one partially cured olefinic elastomer, selected from the group consisting of elastomeric ethylene-propylene copolymer, elastomeric ethylene-propylene copolymers, elastomeric ethylene-propylene terpolymers, polyisoprene, polyisobutylene, polybutadiene, and natural rubber; wherein said partial cure of the elastomer is attained by a curing agent comprising about 1 to 99 percent of the amount necessary for a substantially complete cure.
