ABSTRACT:
A process for preparing an interpolymer of one or more olefins with carbon monoxide is disclosed. The process, which comprises reacting the olefin(s) with carbon monoxide in the presence of a palladium catalyst prepared by reacting together for example palladium acetate, 1,3-bis (diphenylphosphino)propane and para- toluenesulphonic acid, is improved by having an amide or nitrile present. The presence of an amide or nitrile improves reaction rates and reduces the amount of catalyst incorporated into the polyketone. A preferred additive is dimethylformamide.
