    摘要: In a rapid and non-invasive method for characterizing aromatic polycarbonates, fluorescence intensities are determined at least two wavelength ranges and used to calculate a compositional or physical property of the sample. The method is suitable for determining the relative amounts of linear and branched polycarbonates, and it is fast enough to monitor the progress of polymerization reactions.
