    摘要： A process for the preparation of a linear alternating copolymer of carbon monoxide with ethene and another olefinically unsaturated compound (A) wherein a copolymer of which the molar ratio (r.sub.1) of the monomer units originating in the olefinically unsaturated compound A to the monomer units originating in ethene is in the range of from 1:100 to 1:3, is prepared by contacting the monomers in the presence of a liquid diluent with a catalyst composition which is based on (a) a source of a Group VIII metal, and (b) a bidentate ligand of the general formula R.sup.1 R.sup.2 M.sup.1 --R--M.sup.2 R.sup.3 R.sup.4 (I) wherein M.sup.1 and M.sup.2 independently represent a phosphorus, arsenic or antimony atom, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently represent unsubstituted or substituted hydrocarbyl groups and R represents a bivalent bridging group which consists of three atoms in the bridge of which the middle atom is a carbon or silicon atom which carries two monovalent substituents R.sup.5 and R.sup.6 consisting of carbon, hydrogen and optionally oxygen, and the two outer bridging atoms are carbon atoms, while the quotient r.sub.2 /r.sub.1 is less than 24, in which quotient r.sub.1 is as defined herein and r.sub.2 is the molar ratio of the olefinically unsaturated compound A to ethene in the liquid phase.
