Abstract: A method for the production of polyurethane products using very low unsaturation polyether polyols prepared in the presence of aluminum phosphonate catalysts is disclosed. Reaction products of the process include various polyurethane products including foams, coatings, adhesives, sealants and elastomers. The aluminum phosphonate catalyst preferably has a general structure of RPO-(OAlR'R'')2, wherein O represents oxygen, P represents pentavalent phosphorous, Al represents aluminum, R comprises a hydrogen, an alkyl group, or an aryl group, and R' and R'' independently comprise a halide, an alkyl group, an alkoxy group, an aryl group, or an aryloxy group.

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.
