摘要： The present invention relates to methods and devices for in-situ measurement of reaction components of interest during manufacturing of polycarbonate by melt polymerization. The present invention describes irradiating a molten polymer sample with UV/visible light, and generating an absorbance profile correlated to Fries products as well as uncapped phenolic groups in the sample. The methods and apparatus of the invention are suitable for monitoring of Fries products in reactions ranging in size from small scale combinatorial formats to production scale reactors. Also included in methods of the invention are univariate and multivariate analysis for prediction of linear Fries, branched Fries and uncapped phenolic end-groups in unknowns.

摘要： The invention comprises UV/visible spectroscopic analysis of polycarbonate composition. The method comprises determination of the concentration of Fries products, as either total Fries products or as separate determinations of linear and branched components. The method also allows for simultaneous determination of uncapped phenolic end-groups. Determinations may be performed at a single wavelength or over the entire absorption band. The method is suitable for measuring of Fries products in samples ranging in size from small scale combinatorial formats to production scale reactors. The method is independent of reaction variables such as polymer molecular weight, reactor type, and reaction temperature.

摘要： Methods and sensors for selective fluid sensing are provided. A sensor includes a resonant inductor-capacitor-resistor (LCR) circuit and a sensing material disposed over a sensing region. The sensing region comprises at least a portion of the LCR circuit. Temperature-dependent response coefficients of inductance L, capacitance C, and resistance R properties of the LCR circuit and the sensing material are at least approximately 5 percent different from one another. The difference in the temperature-dependent response coefficients of the properties of the LCR circuit and the sensing material enables the sensor to selectively detect analyte fluids from an analyzed fluid mixture substantially independent of temperature.
