  • Processing polyethylenes
    Patent number: 6620895
    Abstract: Polyethylenes made from ethylene and a series of &agr;-olefins using a catalyst that copolymerizes ethylene and &agr;-olefins usually have excellent melt processing characteristics, especially in uses where high zero shear viscosity and low high shear viscosity are desirable. These polyethylenes are preferably made by forming the &agr;-olefins in situ from ethylene during the polymerization process. The polyethylenes are especially useful in blow molding, extrusion or extruded blown film processes.
