| titleOfInvention |
Late-addition catalyst formulation, reactor system, and method for producing polycarbonate |
| abstract |
The present invention provides a melt polymerization reactor system and method of producing polycarbonate using a late-addition catalyst formulation having a melt transesterification catalyst dispersed in a liquid carrier system which preferably includes less than 10 wt % water. The formulation also preferably includes a liquid carrier system having phenol and a cosolvent. The melt transesterification catalyst can be present in the formulation in a range of 50 ppm to 60,000 ppm. |
