Abstract:
A loop/slurry polymerization process comprising contacting in a reaction zone, at a temperature within a range of about 150.degree. F. to about 180.degree. F. in the presence of a hydrocarbon diluent having three or four carbon molecules per molecule, and in the absence of hydrogen:a) ethylene monomer;b) a catalyst system comprising a magnesium compound and a titanium halide, wherein both the magnesium compound and the titanium halide are supported on an inorganic oxide support and said catalyst system has a particle size within a range of about 1 to about 40 microns; andc) an aluminum alkyl cocatalyst;and recovering a homopolymer of ethylene, wherein said homopolymer of ethylene has a weight average molecular weight greater than about one million (1,000,000) and a high load melt index of 0 g/10 minutes.
