A copolymer of carbon monoxide with an acetylenically unsaturated compound and optionally an olefinically unsaturated compound, on the understanding that the copolymer is not a copolymer of carbon monoxide and exclusively acetylene which contains less than 15%-mole of monomer units originating in carbon monoxide and which is obtainable by copolymerizing the monomers in the presence of a catalyst of titanium tetrabutoxide and triethylaluminium; and a process for copolymerizing an acetylenically unsaturated compound and optionally an olefinically unsaturated compound with carbon monoxide, wherein the monomers are contacted with a catalyst composition based on:

Polymer of an acetylenically unsaturated compound

A process for the preparation of acetals by reacting one or more ethylenically unsaturated compounds with carbon monoxide, hydrogen and a liquid or dissolved organic nucleophilic compound containing at least two vicinal hydroxy groups in the presence of a catalyst system comprising:

Preparation of acetals

It is disclosed a linear random copolymer of carbon monoxide and one or more olefinically unsaturated compounds wherein the polymer chain contains units originating from the olefinically unsaturated compound(s) and monomer units originating from carbon monoxide in a molar ratio of from 52.5:47.5 to 80:20. It is further disclosed a process for the preparation of linear random copolymers of carbon monoxide and one or more olefinically unsaturated compounds, wherein the monomers are contacted with a catalyst composition comprising a source of palladium and an anionic phosphorus monodentate ligand in a molar ratio of carbon monoxide to the olefinically unsaturated compound(s) in the range of from 1:30 to 1:3.

Copolymers of carbon monoxide and an olefinically unsaturated compound

Process for the hydroformylation of ethylenically unsaturated compounds, by reaction with carbon monoxide and hydrogen in the presence of a catalyst based on a metal of the platinum group, a source of anions and a bidentate ligand of the formula R.sup.1 R.sup.2 M.sup.1 RM.sup.2 R.sup.3 R.sup.4 wherein M.sup.1 and M.sup.2 are phosphorus, arsenic or antimony, R is a bivalent organic bridging group with 1 to 4 atoms in the bridge, R.sup.1 and R.sup.2 together represent a bivalent cyclic group and R.sup.3 and R.sup.4 independently represent an optionally substituted hydrocarbyl group or together have the same meaning as R.sup.1 and R.sup.2.

Hydroformylation process

A process for the carbonylation of ethylenically unsaturated compounds by reaction with carbon monoxide and a co-reactant in the presence of a substantially non-acidic catalyst system based on a palladium compound and a bidentate ligand of the formula

Carbonylation process

A process for the polymerization of actylenically unsaturated compounds by contacting the monomer(s) under polymerization conditions with a catalyst system comprising: a) a source of cations of one or more Group VIII metals; b) a bidentate ligand containing phosphorus, arsenic and/or antimony; and c) a source of anions.
