PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE

摘要

In a process for producing high molecular weight polyethylene, ethylene is contacted with a slurry of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand under polymerization conditions comprising a temperature of about 20 °C to less than 90 °C and a pressure of about 4 bar to about 40 bar.
