Abstract

Ethylene copolymers having a density of from 0.900 to 0.940 g/cm<3>, are prepared by copolymerizing ethylene with another unsaturated hydrocarbon monomer(s) in the presence of a catalyst comprising a titanium and/or vanadium compound and an organoaluminium compound supported on a magnesium compound, the copolymerization being carried out in a liquid phase comprising the unsaturated hydrocarbon comonomer.
