| titleOfInvention | Preparation of catalyst solution |
| abstract | A process for the preparation of a solution of a catalyst system, suitable for use in a process for copolymerizing carbon monoxide and one or more ethylenically unsaturated compounds, which comprises (a) combining a palladium compound, a bisphophine of the general formula R?1R2P-R-PR3R4¿ (I) wherein each of R?1, R2, R3 and R4¿ independently represents an aromatic hydrocarbyl group which is substituted with an alkoxy group and R represents a bivalent bridging group containing at least two carbon atoms in the bridge, and a lower aliphatic alcohol as solvent, and (b) admixing the obtained combination after a generation period G, during which a temperature T in the range of 0-70 °C is maintained, with an acid, whereby the said generation period G is selected such that the value for G (in hours) and the temperature T (in °C) are related as G « 6.0 x 10-21 exp (14500 / T + 273.2). |
