Abstract
A catalyst active in the preparation of alternating olefin/carbon monoxide (CO) copolymers is constituted by: PA0 (a) at least one salt of a metal of Group IB of the Periodic System, PA0 (b) a mono or bidentate ligand base containing one or two nitrogen or phosphorus atoms capable of linking to the metal atom by means of dative bonds, PA0 (c) a mineral or organic oxidizer agent. Also disclosed are the preparation of the catalyst and the use of said catalyst in alternated copolymerization of ethylene (C2) and/or other olefins with carbon monoxide (CO).
