Abstract
Thermoplastic olefinic, polymer blends which have superior physical properties and adherence for coating materials such as paints are disclosed. The blends may be formed from various combinations of homopolymers of propylene having an isotactic index >0.93, and/or crystallinity >56%, sequentially polymerized blends of polypropylene and ethylene-propylene copolymers, copolymers of ethylene and butene produced with Kaminsky catalysts, and copolymers of ethylene and octene produced with Kaminsky catalysts with C.sub.3 -C.sub.15 alpha olefins.
