  • Thermoplastic polypropylene blends with mixtures of ethylene/butene and ethylene/octene copolymer elastomers
    Patent number: 5998524
    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 polymer, 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.
    Type: Grant
    Filed: October 29, 1997
    Date of Patent: December 7, 1999
    Assignee: Solvay Engineered Polymers
    Inventors: Satchit Srinivasan, Edward Szczepaniak, Sunit S. Shah, David K. Edge

  • Thermoplastic polypropylene blends with mixtures of ethylene/butene and ethylene/octene copolymer elastomers
    Patent number: 5763534
    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.
