Abstract
Process for the preparation of elastomeric amorphous copolymers of ethylene, an alpha-olefin with 3 to 18 carbon atoms and, optionally, a hydrocarbon diene, by copolymerization of the monomers in the presence or in the absence of an inert diluent, at a temperature comprised between -30ºC and -150º c, with the aid of a halogen-containing catalyst obtained from (a) a metal-organic compound of al, and (b) a tri- to pentavalent vanadium compound, characterized by adding to the catalyst system, as an activator a derivative of monochloro- or dichloro- or monobromo- or dibromomalonic acid, chosen from the group consisting of the esters, halides and amides of said acids.
