Abstract Rheological data on polystyrene samples processed for long periods under various mechanical stresses are presented. The data indicate that thermomechanical degradation occurs and that the rate of thermal degradation is increased by the applied stress. Moreover degradation does not reach a limiting value even at high processing times.
