Abstract
The present invention is directed to a method for reducing the percent decomposition of an aromatic carbonate in a first reaction mixture comprising the aromatic carbonate, the method comprising the step of adding at least one decomposition-reducing additive to the first reaction mixture, so as to produce a second reaction mixture in which the percent of the aromatic carbonate present in the second reaction mixture after a predetermined amount of time is greater than the percent of the aromatic carbonate that would be present in the first reaction mixture in the absence of adding the decomposition-reducing additive, after the same predetermined amount of time.
