Robust process for the synthesis of polyestercarbonates |
| abstract |
The present invention related to a method for preparing a polyestercarbonate, the method comprising:a) reacting a dihydric phenol and a diacid having from 12 to about 30 carbon atoms in the presence of an effective amount of carbonate precursor, thereby forming a reaction mixture, wherein the pH of the reaction mixture is maintained in an initial pH range of from about 8.5 to about 9.5 for about 50% to about 95% of the total carbonate precursor addition, and a second pH range of from about 10 to about 12 for the remainder of the carbonate precursor addition. |
