ABSTRACT:
A process for making an epoxide polymer comprises polymerizing an epoxide in the presence of an activated polyurethane foam-supported double metal cyanide (DMC) catalyst prepared by (a) exposing a DMC compound to an epoxide and a hydroxyl group-containing starter to activate the DMC compound, (b) isolating the activated DMC compound from the mixture, and .COPYRGT. reacting a polyol, polyisocyanate and water in the presence of a surfactant, a foaming catalyst and the activated DMC compound to produce the activated polyurethane foam-supported DMC catalyst.
