  • Patent number: 7268204
    Abstract: A method of forming a polyethercarbonate polyol enhances incorporation of CO2 into the polyethercarbonate polyol. The method provides a catalyst including a multimetal cyanide compound. The multimetal cyanide compound has an ordered structure defined by a cationic catalytic center and an anionic backbone with the anionic backbone spatially arranged about the cationic catalytic center. The anionic backbone is modified with a supplemental anionic spacer to affect the spatial arrangement and catalytic activity of the cationic catalytic center. The supplemental anionic spacer is incorporated into the multimetal cyanide compound to establish the general formula, M1a[M2b(CN)cMd3Xe]f, wherein M1, M2, and M3 are various metal ions and X is the supplemental anionic spacer. An H-functional initiator, an alkylene oxide, and CO2 are reacted in the presence of the modified multimetal cyanide compound to form the polyethercarbonate polyol.
