| titleOfInvention | Synthetic method for producing polycarbonate polyol by using double catalysts |
| abstract | The invention relates to a synthetic method for producing polycarbonate polyol by using a double catalyst and a product thereof. The polycarbonate polyol is obtained by the ester exchange reaction of the component A polyol or lactone and the component B carbonate under the action of organic amine and an organic metal double catalyst. The synthetic method has the advantages of high reaction speed, stable composition of extracted fractions, less catalyst residue and reduction or avoidance of post-treatment. |
