The present invention is directed to supported catalyst having utility in the polymerization and co-polymerization of epoxide monomers, said supported catalyst having the general Formula (I):

[DMCC]*b Supp  (I) wherein: [DMCC] denotes a double metal cyanide complex which comprises a double metal cyanide (DMC) compound, at least one organic complexing agent and a metal salt; Supp denotes a hydrophobic support material; and, b represents the average proportion by weight of said support material, based on the total weight of [DMCC] and Supp, and is preferably in the range 1 wt. %≤b≤99 wt. %.
