摘要： Bimetallic catalyst for producing polyethylene resins with a bimodal molecular weight distribution, its preparation and use. The catalyst is obtainable by a process which includes contacting a support material with an organomagnesium component and carbonyl-containing component. The support material so treated is contacted with a non-metallocene transition metal component to obtain a catalyst intermediate, the latter being contacted with an aluminoxane component and a metallocene component. This catalyst may be further activated with, e.g., alkylaluminum cocatalyst, and contacted, under polymerization conditions, with ethylene and optionally one or more comonomers, to produce ethylene homo- or copolymers with a bimodal molecular weight distribution and improved resin swell properties in a single reactor. These ethylene polymers are particularly suitable for blow molding applications.

摘要： Provided are ethylene-based polymer compositions, articles made therefrom, and methods of making the same. Ethylene-based polymer compositions include blends of a linear low density polyethylene prepared with metallocene catalyst and a low density polyethylene. The linear low density polyethylene may optionally have about five mole percent or less of monomer units derived from an alpha-olefin comonomer. Articles composed of such ethylene-based polymer compositions, such as blown films, exhibit favorable physical properties, including excellent optical properties and retained strength i.e., mitigation of expected decline in physical strength due to LDPE addition.
