Abstract

A catalyst active in the polymerization of ethylene and in the copolymerization of ethylene with unsaturated monomers comprises a complex catalyst of nickel, bound to a polystyrene support, definable by the general formula (I): <IMAGE> where Ph, X, R and from R1 to R5, m and n have the meaning stated in the description. The preparation of the catalyst and its use in the polymerization of ethylene and in the copolymerization of ethylene with other unsaturated monomers are described.
