  • Ethylene-based polymer compositions with improved processability
    Patent number: 11384226
    Abstract: The invention provides a composition comprising the following components: A) a first composition, wherein the first composition comprises a first ethylene-based polymer and a second ethylene-based polymer, and wherein the ratio of the “high load melt index (I21) of the first composition” to the “high load melt index (I21) of the first ethylene-based polymer” is greater than, or equal to, 40, and B) one or more azide compounds present in an amount greater than, or equal to, 50 ppm, based on the weight of the first composition.
    Type: Grant
    Filed: February 10, 2014
    Date of Patent: July 12, 2022
    Assignee: Dow Global Technologies LLC

  • Ethylene-based polymers and compositions, methods of making the same and articles prepared therefrom
    Patent number: 8679602
    Abstract: The invention provides an ethylene-based interpolymer comprising the following features: a) density from 0.910 to 0.930 g/cc; b) melt index (I2) from 0.1 to 0.5 g/10 min; and c) a high density fraction in an ATREF short chain branch distribution (SCBD) curve, eluting above 92° C., of greater than 10 percent to less than 28 percent of the total ATREF SCBD curve area. The invention also provides a composition comprising an ethylene-based interpolymer that comprises the following features: a) a density from 0.919 to 0.928 g/cc; b) a melt index (I2) from 0.1 to 0.8 g/10 min; and c) a high density fraction in an ATREF short chain branch distribution (SCBD) curve, eluting above 92° C., of greater than 10 percent to less than 28 percent of the total ATREF SCBD curve area. The invention also provides a hollow tube comprising at least one component formed from a composition comprising an ethylene-based interpolymer that comprises the following features: a) a density from 0.919 to 0.
