PROCESS FOR THE PREPARATION OF A COPOLYMER OF ETHYLENE

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 pres...

Zusammenfassung: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 aluminum; at least one activator, as such, selected from compounds containing chlorine.
