Abstract: An improved, continuous, gas-phase process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon in the presence of a supported catalyst composition, the catalyst composition being formed from a compound of palladium, a Lewis acid and a bidentate ligand of phosphorus, includes return to the polymerization reactor of relatively small particles of polyketone polymer products after catalyst composition has been supplied to the particles.

Abstract: The invention relates to a process for the separation of colloidal barium phosphate or colloidal barium sodium phosphate, used as a heterogeneous catalyst in the alkoxylation of an active hydrogen containing organic compound, from the alkoxylated product, which process comprises contacting the alkoxylated product with an amount of water sufficient to break the colloidal state of the barium phosphate or barium sodium phosphate, and collecting the phosphate.

Abstract: A process for the preparation of polymers comprising a linear alternating polymer of carbon monoxide and at least one olefinically unsaturated hydrocarbon, in the presence of a diluent consisting of one or more lower aliphatic alcohols where water has been added to the solution of a catalyst.

Abstract: Alkylene oxide adducts of organic compounds having active hydrogen atoms are prepared by a process which comprises contacting and reacting an alkylene oxide reactant comprising one or more vicinal alkylene oxides with an active hydrogen containing reactant comprising one or more compounds having active hydrogen atoms in the presence of a catalytically effective amount of sodium barium phosphate or potassium barium phosphate. The product alkoxylates are known to be useful, for instance, as nonionic surfactants, wetting and emulsifying agents, solvent, and chemical intermediates.
