Abstract
The thermal stability and kinetics parameters of polycarbonates and polythiocarbonates derived from diphenols with chlorine atoms in the aromatic rings were studied, showing that polycarbonates have a higher thermal stability than the polythiocarbonates. All polymers degraded in a single stage in the considered temperature range, and the kinetics parameters were determined by using the Arrhenius relationship and a computer program. Polycarbonates degraded by a zero order kinetics, while polythiocarbonates by a first order kinetic.
