  • Patent number: 8653193
    Abstract: A polymeric composition that is suitable for use as a film or a coating. The polymeric composition comprises: (a) a first component comprising copolymer derived from ethylene and one or more C3 to C20 ?-olefin comonomers. The first component has a density of about 0.911 to about 0.918 g/cm3, a compositional distribution breadth index (CDBI) of about 60% to about 85%, a melt index (MI) of about 16.0 to about 30.0 g/10 min, a molecular weight distribution (MWD) of about 1.5 to about 4.0, and a melt index ratio (MIR) of less than about 25; and (b) a second component comprising a low density polyethylene (LDPE). The second component has a g? of about 0.8 to about 0.15 and a MI that is lower than the MI of the first component.

  • Patent number: 5320798
    Abstract: Processing, particularly extruding polyolefins having low MI, narrow MWD at extrusion temperatures less than about 200.degree. C. and at shear rates less than about 2000 sec.sup.-1 but immediately above the shear rate corresponding to the end of the slipstick region of the polyolefin produces a new window of processing conditions to produce smooth polymers that do not have sharkskin melt fracture or wavy surfaces.
