Abstract: Disclosed is a method for the preparation of FCHC-free polyurethane soft (molded) foam materials with low density, by reacting (A) liquid polyisocyanate mixtures containing bound urethane groups, containing 22 to 30 weight percent of NCO groups, which in turn are prepare by reacting a mixture of diphenylmethane-diisocyanate and polyphenyl-polymethylene-polyisocyanates (raw MDI) with at least one polyoxypropylene-polyoxyethylene-polyol with a functionality between 2.5 and 3.6, a hydroxyl number between 50 and 90 and a polymerized ethylene oxide group concentration ranging from more than 30 to less than 50 weight percent, relative to the weight of the polymerized ethylene oxide and 1,2 propylene oxide groups, or by reacting of 4,4' diphenylmethane-diisocyanate (MDI) or an MDI-isomeric mixture with the above-named polyoxypropylene-polyoxyethylene-polyol to form an NCO-group-containing quasi-prepolymer, and diluting this quasi-prepolymer with raw-MDI, with (B) higher-molecular polyhydroxyl compounds and, if appropriate, (C) low-molecular chain lengthening and/or cross-linkage promoting materials, in the presence of (D) propellants, (E) catalysts as well as, if appropriate, (F) auxiliary materials and/or additives.

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.

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.
