Abstract: An improved fiber reinforced polyoxymethylene molding composition is provided which when molded forms a composite article having improved physical properties (e.g., tensile strength and Izod impact strength). In admixture with the polyoxymethylene polymer and fibrous reinforcement (e.g., glass fiber) is provided a minor amount (as defined) of a certain polycarbodiimide (as defined) or a combination of the polycarbodiimide and a high molecular weight thermoplastic phenoxy resin. It is believed that the polycarbodiimide either alone or in combination with the thermoplastic phenoxy resin functions primarily by a complex mechanism which is incapable of simple explanation to enhance the adhesion between the chemical functionality of the oxymethylene polymer chain and the fibrous reinforcement.

Abstract: This invention provides an improved process for converting methanol into ethanol and ethanol precursors with higher efficiency than prior art methods. This invention further provides a novel heterogeneous co-catalyst system adapted for alkanol homologation which consists essentially of cobalt carbonyl and rhenium metal.

Abstract: An ethylenically unsaturated hydrocarbon is hydroformylated to an aldehyde having one more carbon than the unsaturated hydrocarbon by contacting the unsaturated hydrocarbon, carbon monoxide and hydrogen in the presence of a reaction medium comprising a Group VIII noble metal and a bicyclo or tricyclo(heterocyclo) saturated amine having 2 to 10 carbons, 1 to 4 nitrogens and at least one nitrogen in a bridgehead position. Liquid phase contacting is employed with the catalyst dispersed in a liquid phase at temperatures from 50.degree. to about 200.degree. C. and pressures from 1 to 300 atmospheres. A typical reaction comprises contacting ethylene, carbon monoxide and hydrogen at a temperature of about 88.degree. C. and a pressure of 50 atmospheres with an inert liquid reaction medium containing rhodium chloride and triethylenediamine. Preferably the reaction medium also contains a biphyllic ligand which is a trivalent phosphorus, antimony or arsenic organic compound.

Abstract: Aqueous polymeric emulsions are formed by the inter-polymerization reaction product of at least one monomer having a reactive CH.sub.2 =C< group (e.g., vinyl acetate and alkyl acrylates) and an alkyd resin which is modified by the incorporation therein of certain ethylenically unsaturated monomers.
