Abstract:
A method for reducing the percent decomposition of an aromatic carbonate in a first reaction mixture comprising said aromatic carbonate, at least one first metal source selected from the group consisting of a Group 8 metal source, a Group 9 metal source and a Group 10 metal source; and at least one second metal source selected from the group consisting of a Group 11 metal source and a Group 14 metal source, the method comprising the step of adding at least one decomposition-reducing additive to said first reaction mixture so as to produce a second reaction mixture in which the percent of said aromatic carbonate present in said second reaction mixture after a predetermined amount of time is greater than the percent of said 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.
