Preparation of ethylene-propylene |
abstract |
A soft or semi-hard ethylene- propylene copolymer having a melt index of 0.01 to 10 and a density of 0.850 to 0.910 is obtained by copolymerising ethylene, 15 to 250 mol% thereof of propylene, and optionally a diene in a substantially solvent-free vapor phase condition and in the presence of a catalyst consisting of a solid substance and an organoaluminium compound, said solid substance containing a magnesium-containing inorganic solid compound and a titanium compound and/or a vanadium compound. |
