ABSTRACT:
A process for preparing interpolymers of an olefin(s) and carbon monoxide (polyketones) is provided. The process employs a palladium catalyst prepared by reacting together a palladium source, a bidentate amine, phosphine, arsine or stibine and a source of a borate anion. The catalyst effects fast polymerization of the olefin(s) and carbon monoxide in, e.g. methanol or ethoxyethanol solvent. By using the catalyst a lower catalyst deactivation on recycle is observed relative to previously described systems.
