In another embodiment, a process of purifying an interfacially polymerized polycarbonate from a feed comprising an aqueous phase and an organic phase comprising an organic solvent, the interfacially polymerized polycarbonate, a catalyst, and ions, can comprise: separating the aqueous phase and the organic phase from the feed, wherein during the separating the feed is subjected to at least one of: energy of less than or equal to 0.5 kJ/kg of feed, a shear rate of less than 150,000 S −1 , and centrifugal forces of 100 to 2,000 g-force; to form a purified aqueous phase and a purified organic phase comprising a purified polycarbonate. |
