Preparation of ethylene-propylene copolymers |
| abstract |
Ethylene-propylene copolymers having a melt index of 0.01 to 1 and a density of 0.910 to 0.945 are produced by vapor-phase polymerisation by copolymerising ethylene with 6 to 100 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 an organoaluminium compound and a solid substance containing a magnesium-containing inorganic solid compound and a titanium compound and/or a vanadium compound. |
