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 homopolymers of propylene having an isotactic index which is greater than about 0. 93, and/or a crystallinity which is greater than about 56%, and sequentially polymerized blends of polypropylene and ethylene-propylene copolymers, with elastomeric components such as copolymers of ethylene and butene produced with metallocene or Kaminsky catalysts, and copolymers of ethylene and octene produced with metallocene or Kaminsky catalysts. If desired, other components, such as copolymers of ethylene with C. sub. 3 -C. sub. 15 alpha olefins or fillers, can be included.
