ABSTRACT:
The polymerization of epoxides such as propylene oxide to polyether polyols is conducted in the presence of a polyurethane foam-supported double metal cyanide (DMC) catalyst comprising a DMC catalyst such as zinc hexacyanocobaltate which can contain a slight excess of a metal halide salt to attain crystallinity, and a polyurethane foam support.
