ABSTRACT:
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, preferably propylene, includes an aromatic amine in the catalyst composition formed from a palladium salt, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus. The presence of the aromatic amine reduces the proportion of 3-alkyl-2,5-furandiyl moieties present in the polymer chain.
