Notes:
A liquid chromatographic method for the oligocarbonates and chloroformate-containing oligomers at various stages in a typical polycarbonate phosgenation reaction has been developed. The accurate measurement of various types oligomers during phosgenation should allow for a better understanding of polymerization mechanism and provide great aid in defining the critical process parameters. Comparison of the total choloroformate concentration by accumulating every individual chlorofor-mate-containing componenent and the standard colorimetric method shows close agreement.
