A process for the slurry polymerization of ethylene

摘要

A loop/slurry olefin polymerization process is provided which produces ultra high molecular weight ethylene homopolymer. The process is carried out at a temperature within a range of 66 to 82 DEG C, in the presence of a hydrocarbon diluent, in the absence of hydrogen, with a catalyst system comprising a magnesium compound and a titanium halide both supported on an inorganic oxide, and an aluminium alkyl cocotalyst.
