METHOD FOR PRODUCING ALIPHATIC POLYCARBONATE |
摘要 |
The present invention provides an aliphatic polycarbonate production method which, using carbon dioxide and an epoxide, easily produces aliphatic polycarbonates having a low metal catalyst content. The invention relates to an aliphatic polycarbonate production method which includes a step of polymerization by reacting carbon dioxide with an epoxide in the presence of a metal catalyst; and a step of treating a polymer obtainable in the polymerization step with a surfactant. High-purity aliphatic polycarbonate having a low metal catalyst content can be easily provided by the aliphatic polycarbonate production method of the invention. |
