摘要：In a process for producing polyethylene, ethylene is contacted under
polymerization conditions with a slurry of a catalyst composition comprising a particulatesupport and a Group 4 metal complex of a phenolate ether ligand carried by the supportand present in an amount so as to provide about 0.1 to about 35 μι&eegr;o of Group 4metal per gram of the support. The resultant polyethylene has a molecular weight of atleast 3×105 g/mol as determined by ASTM 4020, an average particle size, d50, of less 300microns, preferably about 100 to 250 microns, and a span, log10(d90/d10), of less than0.4.
