  • Patent number: 10442879
    Abstract: An impact copolymer comprising a polypropylene comprising at least 50 mol % propylene, and having a molecular weight distribution (MwMALLS/Mn) greater than 10, a branching index (g?) of less than 0.97, and a melt strength greater than 40 cN, and an elastomer. Also disclosed is a method of making an impact copolymer composition comprising melt-blending the components, sequentially or simultaneously a polypropylene resin comprising at least 50 mol % propylene, and having a molecular weight distribution (Mw/Mn) greater than 6, a branching index (g?) of at least 0.97, and a melt strength greater than 10 cN determined using an extensional rheometer at 190° C.; and within the range from 0.01 to 3 wt % of at least one organic peroxide; and an elastomer.

  • Patent number: 10227483
    Abstract: Polymer blends comprising at least one olefin block copolymer such as poly(ethylene-b-ethylene/propylene-b-ethylene), and at least one propylene-based elastomer such as a propylene-ethylene random copolymer, such blends useful in elastic hygiene articles. The blends have improved permanent set compared to the propylene-based elastomer alone.

  • Publication number: 20170306135
    Abstract: Disclosed is a method of forming a thermoplastic polyolefin composition, and the TPO itself, comprising discrete ?-olefin copolymer domains within a continuous phase of polypropylene comprising combining within the range from 8 wt % to 60 wt % of the ?-olefin copolymer, by weight of the thermoplastic polyolefin, and within the range from 92 wt % to 40 wt % of the polypropylene by weight of the thermoplastic polyolefin, wherein the complex viscosity of the ?-olefin copolymer (CV?-olefin) and polypropylene (CVPP) satisfy the formula 0.2?CV?-olefin/CVPP?5 when the CVs are measured at the same frequency and temperature.
