  • Blow Molding Polymers with Improved Cycle Time, Processability, and Surface Quality
    Publication number: 20220275183
    Abstract: Ethylene-based polymers having a density of 0.952 to 0.965 g/cm3, a high load melt index (HLMI) from 5 to 25 g/10 min, a weight-average molecular weight from 275,000 to 450,000 g/mol, a number-average molecular weight from 15,000 to 40,000 g/mol, a viscosity at HLMI from 1400 to 4000 Pa-sec, and a tangent delta at 0.1 sec?1 from 0.65 to 0.98 degrees. These polymers have the processability of chromium-based resins, but with improved stress crack resistance, and can be used in large-part blow molding applications.
    Type: Application

  • Ethylene-Propylene Copolymer Compositions and Methods of Making and Using Same
    Publication number: 20080114142
    Abstract: An ethylene-propylene copolymer having a cold xylene solubles weight percent greater than twice the magnitude of the ethylene content wherein the ethylene content is measured by C13-NMR and having less than about 30% of the cold xylene solubles fraction having a log weight average chain length of less than about 1000 wherein the weight average chain length is measured by gel permeation chromatography.
