Abstract
The invention relates to compositions that may be used as catalysts for the preparation of polymers of carbon monoxide and olefinically unsaturated hydrocarbons. The invention also relates to processes using the catalyst compositions of the invention to prepare said polymers. The processes comprise contacting the monomers in the presence of a catalyst obtained from the reaction of a Group VIII metal compound with a nitrogen bidentate ligand, and an anion of a non-hydrohalogenic acid having a pKa of less than 6.
