Double metal cyanide complex catalyst for ring opening polymerization of alkylene oxide and its production process |
| abstract |
A process for producing a double metal cyanide complex catalyst for ring opening polymerization of alkylene oxide, which comprises subjecting a substantially crystalline double metal cyanide compound to a contact treatment by heating at from 45 to 125° C. with an aqueous solution containing an organic ligand and a metal salt, and then separating the resulting solid from the obtained slurry. |
