Double Metal Cyanide Catalyst and Epoxide/Carbon Dioxide Copolymer Prepared Using the Same

摘要

Provided are a double metal cyanide (DMC) catalyst used in copolymerization of an epoxide/carbon dioxide useful for preparing polyurethane, a foaming agent, an elastomer, a sealant, a coating material, and the like, and an epoxide/carbon dioxide copolymer prepared using the same. In addition, the present invention provides a double metal cyanide (DMC) catalyst prepared us ing an ion-exchange resin without washing alcohol, and an epoxide/carbon dioxide copolymer having a high purity, a high selectivity, and a high carbonate content prepared using the same.
