  • Compatible thermoplastic polyurethane-polyolefin blend compositions
    Patent number: 6632879
    Abstract: A thermoplastic polyurethane/olefin-graft polymer blend with an optional compatibilizing polymer that demonstrates improved tensile strength, compression set and abrasion resistance properties relative to a blend prepared from the same thermoplastic polyurethane and an ungrafted version of the olefin-graft polymer.
    Type: Grant
    Filed: April 14, 2000
    Date of Patent: October 14, 2003

  • Silane-crosslinkable, substantially linear ethylene polymers and their uses
    Patent number: 6048935
    Abstract: Curable, silane-grafted substantially linear ethylene polymers are described which are useful as wire and cable coatings, weatherstripping, fibers and the like. These silane-grafted polymers can be either filled or unfilled and cure quickly relative to many commercial coatings.
    Type: Grant
