ABSTRACT:
Foam-supported double metal cyanide (DMC) catalysts are disclosed as useful catalysts for epoxide polymerization. Polyurethane foam-supported catalysts of the invention are more active and show reduced induction periods compared with conventional powdered DMC catalysts. The catalysts of the invention can be recovered from the epoxide polymer products and can be reused to catalyze additional epoxide polymerizations.
