A process for preparing an aromatic polycarbonate of controlled molecular weight which comprises interfacially reacting in water and an organic solvent, a dihydric phenol, a carbonate precursor and a molecular weight controlling effective amount of a compound of the formula <IMAGE> wherein n is an integer having a value of from 0 to 5 inclusive; Y is a halide or hydroxyl; and each R is independently selected from the group consisting of alkyl radicals, aryl radicals, alkaryl radicals, aralkyl radicals, alkoxy radicals, aryloxy radicals, halides, <IMAGE> radicals wherein R2 is selected from hydrogen, alkyl radicals or acyl radicals or R3 is an acyl radical or -C 3BOND N. The polymers are useful in injection molded articles. |
