T 1446 A B S T R A C T PREPARATION OF POLYMERS AND POLYMER MIXTURES OF CARBON MONOXIDE WITH ONE OR MORE OLEFINICALLY UNSATURATED COMPOUNDS, LINEAR BLOCK POLYMERS AND POLYMER MIXTURES Process for the preparation of polymers and polymer mixtures of carbon monoxide with one or more olefinically unsaturated compounds, wherein a mixture of carbon monoxide with one or more compounds (monomers D) containing in their molecules a cyclohexane . ring of which the carbon atoms 1 and 4 are joined to each other by one oxygen or carbon atom, the carbon atoms 5 and 6 are joined to each other by an olefinic double bond and at least one of the carbon atoms 2 and 3 may carry a hydrocarbyl group as substituent and optionally with one or more .alpha.-olefins (monomers A) with a maximum of four carbon atoms per molecule, is contacted at a temperature of above 100°C and at elevated pressure with a catalyst containing a Group VIII metal and a phosphorus bidentate ligand of the general formula R1R2P-R-PR3R4, in which R1 to R4 are identical or different optionally polarly substituted hydrocarbyl groups and R is a divalent bridging group containing at least two carbon atoms in the bridge.
