ABSTRACT:
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon comprises contacting the carbon monoxide and hydrocarbon under polymerization conditions in the presence of a reaction diluent and a novel catalyst composition formed from a palladium compound, a strong non-hydrohalogenic acid and a tetradentate aromatic phosphine ligand. The polymer products are of higher molecular weight and are produced at a faster rate than the more conventional process employing a catalyst composition formed from a bidentate ligand.
