Abstract
A catalyst active in the preparation of alternating olefin/carbon monoxide (CO) copolymers is constituted by: PA1 (a) Pd(O.sub.2 CNEt.sub.2).sub.2 (NHET.sub.2).sub.2 supported on a solid carrier preferably constituted by hydroxylated silica, PA1 (b) an either mono- or bidentate ligand containing one or two nitrogen or phosphorous atoms capable of linking to Pd atom by dative bonds, PA1 (c) a mineral or organic acid. 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).
