PROCESS FOR THE PREPARATION OF A COPOLYMER OF ETHYLENE |
| 摘要 |
A process for the preparation of an elastomeric polymer of ethylene which comprises polymerizing, in suspension, a mixture of monomers comprising ethylene, at least one a-olefin having from 3 to 12 carbon atoms, possibly at least one non-conjugated diene having from 4 to 20 carbon atoms, in the presence of a catalytic system comprising:—a suspension in oil of at least one catalyst selected from compounds containing vanadium;—-at least one co-catalyst, as such, selected from compounds containing aluminium; at least one activator, as such, selected from compounds containing chlorine. |
