Abstract
Abstract The invention relates to compositions that may be used as catalysts for the preparation of polymers of carbon monoxide and at least one olefinically unsaturated organic compound. The invention also relates to a process using the catalyst compositions of the invention to prepare said polymers. The process comprises contacting the monomers in the presence of a catalyst obtained from the reaction of (a) a Group VIII metal compound with (b) a bidentate phosphorus, arsenic or antimony ligand, (c) a compound selected from the group consisting of non-noble transition metal salts having an anion of a non-hydrohalogenic acid with a pKa less than 6, and (d) a quinone.
