ABSTRACT:
Double metal cyanide (DMC) catalysts useful for epoxide polymerizations are disclosed. The catalysts comprise a DMC compound, an organic complexing agent, and from about 2 to about 80 wt. % of a functionalized polymer or a water-soluble salt derived from the polymer. The catalysts are easy to prepare and isolate, are substantially non-crystalline, and have high activity for polymerizing epoxides. Polyols made from the catalysts have exceptionally low unsaturations, low viscosities, and reduced levels of high molecular weight polyol tail.
