A loop/slurry olefin polymerization process is providednwhich produces ultra high molecular weight ethylene homopolymer.nThe process is carried out at a temperature within a range of 66 ton82°C, in the presence of a hydrocarbon diluent, in the absence ofnhydrogen, with a catalyst system comprising a magnesium compound and antitanium halide both supported on an inorganic oxide, and an aluminiumnalkyl cocotalyst. |
