    摘要: A process for producing an aromatic polycarbonate in a water-in-oil emulsified form, having an improved heat stability during molding at a high temperature, is described. In the process according to the present invention, a tertiary amine is added to the water-to-oil emulsion after the average diameter of liquid droplets of the water phase is reduced to not more than 10.mu.m. The polycarbonate obtained by the process of the present invention is improved in heat stability and can provide a molded article with less coloration.
