Summary

Phenolphthalein polythiocarbonate was obtained by phase transfer catalysis using several catalysts and characterized by inherent viscosity, i.r. spectroscopy, differential scanning calorimetry, and thermogravimetric analysis. From the thermogravimetric curve, the kinetics parameters were determined. Glass transition temperature, thermal decomposition temperature, activation energy, and preexponential factor were lower than those determined for the corresponding polycarbonate.
