Process for preparing branched polycarbonate |
| abstract |
The present invention is a process for producing branched polycarbonate providing for optimum utilization of the branching agent. It was surprisingly found that adding at least a portion of the coupling catalyst to the polymerization at a point during the oligomerization in the reaction results in a higher degree of branching and improved rheological properties. |
