  • Heterogeneous/homogeneous copolymer
    Publication number: 20060041074
    Abstract: Novel polyethylene copolymer compositions prepared with a homogeneous catalyst system are characterized by having a unique high molecular weight, low comonomer (high density) fraction. These heterogeneous/homogeneous compositions may be prepared using a solution polymerization process in which the polymerization reactor contains a gradient in temperature, catalyst concentration or monomer concentration. The heterogeneous/homogeneous compositions of this invention are easily processed into films having excellent tear strengths and low hexane extractables.

  • Ethylene/alpha-olefin copolymer made with a non-single-site/single-site catalyst combination, its preparation and use
    Publication number: 20050054791
    Abstract: An ethylene/?-olefin copolymer comprising a component produced by a non-single-site polymerization catalyst and a component produced by a single-site polymerization catalyst, its preparation and use are described. The copolymer has an ?-olefin content of 5 to 20 percent by weight aud shows at least two CRYSTAF peak temperatures differing by at least 15° C. and/or at least two DSC melting peak temperatures differing by at least 15° C.
