Abstract: The hydrolytic degradation of polycarbonate resins is a first-order process in terms of the decrease in average molecular weights under a relative humidity (RH) and temperature. Two analysis procedures have been developed for making life-cycle predictions of polycarbonate at any combination of humidity and temperature. The first prediction procedure uses an Arrhenius equation derived for determination of the activation energy of polycarbonate hydrolysis tested at various temperatures under a constant RH. The …
