Summary

A liquid Chromatographic method for the oligocarbonates and chloroformate-containing oligomers at various stages in a typical tetrabromobisphenol-A polycarbonate phosgenation reaction has been developed. It has been discovered that triethyl amine, normally used as a catalyst for the polymerization, also acted as a chain terminator producing carbamate end-group oligomers. The characterization of the polymer and various types oligomers during phosgenation should allow a better understanding of polymerization mechanism and provide an important aid in defining the critical process parameters.
