## Abstract

A process for the synthesis of a catalyst for the polymerization of carbon monoxide and at least one olefin which comprises treating a mixture of a compound of palladium, such as tetrakis(acetonitrile) palladium, and a Lewis acid anion, such as a fluoride of a metal selected from Group III to Group V of the Periodic Table (e.g., boron trifluoride), with carbon monoxide and an olefin followed by reaction of the resulting composition with a bidentate ligand reagent, such as a 1,3-bis(diphenyl-phosphino) alkane (e.g., 1,3-bis(diphenyl-phosphino) propane).
