Abstract
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. %.

A 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, two organic complexing agents that are distinct from the other, 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;
- wherein the hydrophobic support material is selected from the group consisting of hydrophobic materials having a methanol wettability value of at least 30 vol. %;
