  • Patent number: 9492963
    Abstract: This invention relates to coupling of polyethylene resins, more specifically coupling of polyethylene resins for use in extruded profiles, especially extruded profiles for sheet extrusion and cut sheet thermoforming applications and geomembranes. The process involves conveying a HDPE resin through an extruder, wherein the extruder comprises a feed zone, a first melt zone downstream of the feed zone, a second melt zone downstream of the first melt zone, and a third melt zone downstream of the second melt zone. The resin is melted in the first zone, contacted with oxygen in the second melt zone, and contacted antioxidant in the third melt zone.

  • Patent number: 8512837
    Abstract: The present invention relates to the use of particular blends of LLDPE and LDPE together with specific fabrication conditions to make foamed sheets of thin gauge with MD tear properties similar to an equivalent gauge non-foamed sheet of the same composition. In particular, blends which combine a high MI LLDPE rich fraction with a low MI branched LDPE minor fraction provide the adequate balance of mechanical strength of the polymer base with its melt strength, extensibility and stress relaxation, allowing a thin foam film with MD tear strength which is comparable to non foamed counterparts of similar gauge and composition. The foamed films of the present invention are thin (generally from about 1 to 10 mils thick), and have an MD tear strength of at least about 160 grams for a 3 mil film as measured by ASTM D 1922. The foamed films of the present invention are preferably made at least in part from blends which comprise from 10 to 95 percent by weight of LLDPE having a relatively high (1.
