  • Use of modified olefin polymers for producing polyolefin products with improved toughness, strength and heat resistance
    Patent number: 6797778
    Abstract: Use of modified olefin polymers for production of polyolefin products with improved toughness, strength and heat resistance. Polyolefin products with high requirements for toughness, strength and heat resistance, produced from modified olefin polymers based on modified propylene polymers which have been modified by reaction with bifunctional monomers in the presence of free-radical generators in the solid phase. The polyolefin products are particularly suitable for shock-absorbing components of motor vehicles, such as bumpers, spoilers and side edge protection elements.
