| titleOfInvention | Method for quenching of catalyst in the production of low molecular weight polycarbonates |
| abstract | Improved performance in high temperature, high vacuum reactors is obtained by quenching alkaline catalyst present in the product a melt polycondensation reaction using a sulfonic acid ester quencher in a carrier. The carrier if formed from a first carrier component effective to solubilize the quencher and having a lower boiling point than the quencher, and a second carrier component soluble in the first carrier component and having a higher boiling point than the quencher. An exemplary carrier composition contains equal parts of diphenylcarbonate and toluene. |
