    Abstract: Un metodo para formar un poliol de polietercarbonato que incorpora CO2 en el poliol de polietercarbonato. El metodo provee un catalizador que incluye un compuesto de cianuro de multiples metales. Un iniciador H-funcional, un oxido de alquileno y CO2 se hacen reaccionar en presencia del compuesto de cianuro de multiples metales en un reactor. El metodo provee ademas un compuesto CO2-filico o un sustituyente CO2-filico. El compuesto y sustituyente CO2-filico mejoran la incorporacion de CO2 en el poliol de polietercarbonato y reduce la formacion de carbonatos de alquileno ciclicos, tales como carbonato de propileno ciclico, que son subproductos indeseables.

    Abstract: Improved methods for synthesizing double metal cyanide (DMC) catalysts are disclosed. These methods combine an aqueous solution of a first metal salt, such as ZnCl2, with an aqueous solution of a second metal salt, such as CoCl2, and with an aqueous solution of an alkali metal cyanide, such as KCN, in different manners to synthesize DMC catalysts, such as Zn3[Co(CN)6]2.

    Abstract: A method of removing and reclaiming a double metal cyanide (DMC) catalyst from a polyol is disclosed. A polymeric acid that is soluble in the polyol is introduced into the polyol during or after the polymerization reaction. The polymeric acid reacts with the double metal cyanide catalyst thereby causing the double metal cyanide catalyst and the polymeric acid to form an agglomeration in the polyol. The agglomeration is easily separated from the polyol via filtration, for example. The recovered agglomerated DMC catalyst can then be reconstituted using an acid solution.
