    摘要: In a process for producing polyethylene having a molecular weight of at least 3×105 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition in at least one hydrocarbon. The catalyst composition comprises a Group 4 metal complex of a phenolate ether ligand and the slurry includes from about 5 to less than 40 ppm per liter of a compound effective to increase the conductivity of said at least one hydrocarbon.

    摘要: In a process for producing an elongated polyethylene component, such as a fiber or membrane, polyethylene powder having a molecular weight of at least 3×105 g/mol as determined by ASTM 4020 is dissolved in a solvent to produce an extrudable solution. The solution is then extruded through a die to form an elongated component and at least part of said solvent is removed from the elongated component. The polyethylene powder used in the process is produced by polymerizing ethylene in the presence of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand.
