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 thermoplastic components such as a crystalline isotactic propylene polymers and sequentially polymerized blends of polypropylene and ethylene-propylene copolymers, with elastomeric components such as copolymers of ethylene and butene, and copolymers of ethylene and octene which are produced with metallocene or Kaminsky catalysts. If desired, other components, such as fillers, can be included. The thermoplastic olefinic, polymer blends are suitable for automotive applications.
