The physical aging of bisphenol A polycarbonate was studied using the differential scanning calorimetry technique. Cowie and Ferguson's model and Williams-Watts function were used to analyze the data. It is confirmed that the relation β¬H Ο± (T a ) Ο β¬C p (T g Οͺ T a ), where β¬H Ο± (T a ) is the value o
The hydrolytic aging of an unstabilized industrial sample of polycarbonate was studied at 40, 70, 80, and 90Β°C, 100% RH. The water absorption characteristics show that, at equilibrium, the polymer absorbs about 0.04 mol water per ester group and that the equilibrium is reached after about 10-40 h ex
