Process for the production of polycarbonate solutions

摘要

The invention relates to a process for the production of solutions of polycarbonates in organic inert solvents which is characterized in that from 2.5 ppm to 100 ppm phosphorous acid, based on the weight of the diphenol used for polycarbonate production, are added to the emulsion of the two phases obtainable by the known two-phase interfacial process and the emulsion is worked up in known manner.
