An ethylene homopolymer having a density of from about 0.956 to about 0.970 g/cm,and a high load melt index (190&deg; C. and 21.6 kg) of from about 7 to about 21 g/10 min. A continuous polymerization process for the production of the ethylene homopolymer, in the presence of a diluent chosen from the group consisting essentially of n-butane, n-hexane, n-heptane, isobutane, isopentane, isooctane, 2,2-dimethylpropane, cyclopentane, cyclohexane and their mixtures, wherein ethylene is brought into contact with a chromium oxide catalyst deposited on an inorganic support containing from about 0.1 to about 5 wt % chromium and activated at a temperature from about 600 to about 900&deg; C., at a polymerization temperature from about 55 to about 150&deg; C., the ethylene concentration in the diluent being from about 1 to about 10 mol %. A composition consisting essentially of the ethylene homopolymer, the composition having a density of from about 0.956 to about 0.970 g/cm,and a high load melt index of from about 5 to about 20 g/10 min. A shaped product manufactured from this composition.
