摘要: The process consists of subjecting a crude polyether polyol produced by catalysis with double metal cyanide (DMC) catalysts to a microfiltration or ultrafiltration process. The resulting polyether polyol is substantially pure, has high transparency and a very low content of DMC catalyst residues.

摘要: The process consists of making react (i) an alkylene oxide polyether polyol, (ii) an organic compound which has an ethylenic unsaturation and a hydroxyl, carboxyl, anhydride, isocyanate or epoxy group and (iii) an alkylene oxide selected from ethylene oxide, propylene oxide and mixtures thereof, in the presence of an effective quantity of a potassium naphthenate catalyst. The unsaturated polyester polyols produced have a reduced degree of unsaturation and are useful in the synthesis of polymeric polyols with good viscosity, filterability and particle size properties, suitable for the production of cellular polyurethane compounds.
