Catalytic system and process for the copolymerization of olefins with carbon monoxide.

摘要

An active catalyst in the preparation of alternating copolymers of olefins with carbon monoxide (CO) and consisting of: a) a metal salt of the group IB of the periodic table; b) a bidentate binder containing two nitrogen or phosphorous atoms capable of binding themselves to the metal atom by means of co-ordination bonds; c) a Lewis acid; d) optionally an oxidizing agent. The preparation of the catalyst is described together with its use in the alternating copolymerization of ethylene (C2) and/or other olefins with carbon monoxide.
