  • Patent number: 9580586
    Abstract: A polymeric composition is a blend of one or more heterophasic copolymers of propylene and ethylene produced by a multistep polymerization, wherein the heterophasic copolymers comprise a low crystalline matrix component and a soft amorphous elastomeric component, in which both the matrix component and the soft amorphous elastomeric component contain greater than 55% by weight propylene; one or more additional elastomeric components selected from the group of an ethylene/?-olefin C3-C20 copolymer with a total ethylene concentration of greater than or equal to 65% by weight; and a propylene/?-olefin C2, C4-C20 copolymer with a total propylene concentration of greater than or equal to 65% by weight; 5-65% by weight of the total composition of one or more inorganic or organic reinforcement materials; and 0.01-4% by weight of the total composition of a maleic anhydride grafted polypropylene compatibilizer or coupling agent. The polymeric composition has a low crystallinity of less than 30 J/gram measured by DSC.
    Type: Grant

  • Patent number: 9115279
    Abstract: The present invention relates to polypropylene compositions with a balance of high strength, good clarity, excellent stress whitening resistance, and excellent impact properties—especially at low temperatures—for use in demanding plastics applications. Blends consist of both homopolymer and random copolymer polypropylene fractions, as well as propylene-ethylene elastomers and styrenic based elastomers. The invention also covers molded articles made from these blends.
