Abstract

PURPOSE: To prepare a high-density polyethylene having excellent qualities and high bulk density, in high efficiency, without removing the catalyst residue from the product, by the use of a catalyst comprising a specific solid product and an organo- aluminum compound.
CONSTITUTION: Ethylene is polymerized under an ethylene pressure of 1W100 kg/cm2, at 50W80°C for 0.5W5 hours, in the presence of a catalyst consisting of (A) a solid product prepared by reacting (a) a solid substance obtained by reacting 50W300 g of a 1W20C magnesium dialkoxide dispersed in 1l of an insoluble solvent, with hydrogen halide introduced into the dispersion at -20W+50°C for 0.5W3 hours, with (b) 1W20 times mole of a titanium halide in the presence of (c) a silicon compound of formula XnSi(OR)4-n (X is halogen; R is alkylen is 0W4), at 30W200°C for 10 min to 6 hours, and (B) an organo-aluminum compound.
