ABSTRACT:
An improved process for the production of polyketone polymers in the presence of a catalyst composition formed from a palladium compound, the anion of certain strong acids and certain bidentate ligands comprises the provision of a controlled proportion of the catalyst composition at the outset of polymerization and providing the remainder of the catalyst composition only when the polymer concentration in the product-containing suspension has reached a minimum value.
