ABSTRACT:
In the process of producing a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon in the presence of a palladium salt, the anion of a strong non-hydrohalogenic acid, and a phosphine ligand, improved polymerization rates are obtained when employing a novel catalyst composition formed from a novel 1,3-bis(phosphino)-2-silapropane, which can be produced with high yield, wherein the 2-silapropane moiety is additionally substituted at the silicon atom with two hydrocarbyl substituents.
