  • Multistage process for producing polyethylene compositions
    Patent number: 9951213
    Abstract: The present invention is a process for producing low density copolymers of ethylene and alpha-olefins having from 4 to 10 carbon atoms in three polymerization stages in the presence of an olefin polymerization catalyst where a low molecular weight copolymer of ethylene is produced in two of the stages and a high molecular weight copolymer in one of the stages. The resulting copolymers have a low density of not more than 920 kg/m3.
    Type: Grant
    Filed: December 12, 2014
    Date of Patent: April 24, 2018
    Assignee: BOREALIS AG

  • Multimodal polymer
    Patent number: 9234061
    Abstract: A multimodal ethylene copolymer with a density of at least 940 kg/m3 having an MFR21 in the range of 1 to 30 g/10 min and a Fmax/?I ratio of less than 60 cN/s; said ethylene copolymer comprising at least three components (I) an ethylene and optionally at least one C3-20 alpha olefin comonomer component forming 30 to 60 wt % of said ethylene copolymer; (II) an ethylene and optionally at least one C3-20 alpha olefin comonomer second component forming 30 to 60 wt % of said ethylene copolymer: and (III) an ethylene and optionally at least one C3-20 alpha olefin comonomer third component forming 3 to 20 wt % of said ethylene copolymer; wherein at least one of components (II) or (III) is a copolymer.
