| titleOfInvention | A kind of preparation method of polycarbonate |
| abstract | The invention provides a preparation method of polycarbonate, which comprises the following steps: mixing butylene oxide, a double metal cyanide catalyst, a cocatalyst and carbon dioxide, and reacting to obtain the polycarbonate. The preparation method adopts a catalytic system of a double metal cyanide catalyst and a co-catalyst to prepare epoxybutylene polycarbonate from butylene oxide and carbon dioxide under relatively mild conditions; and due to the double metal cyanide catalyst and The synergistic effect of the co-catalyst, the preparation method improves the fixed amount of carbon dioxide, reduces the probability of side reactions, and improves the conversion rate of monomers. |
