ABSTRACT:
A process for catalytic homo- or co-polymerization of ethylene under the conditions of a pressure of at least 300 kg/cm.sup.2, a temperature of at least 180.degree. C., a contact time with a catalyst of 10 to 150 seconds and substantial absence of a solvent is disclosed. The catalyst used comprises Components A and B where Component A is a solid composition prepared by mixing and pulverizing (1) a magnesium halide, (2) titanium trichloride, and (3) an electron donor and Component B is an organoaluminum compound containing a halogen.
