PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE

摘要

In a process for producing polyethylene having a molecular weight of at least 3 x 105 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand, wherein the slurry further includes a scavenger comprising an alkyl magnesium compound.
