The influence of relative humidity on polyarylate hydrolysis

The influence of relative humidity (RH), between 55 and 100%, on the rate of hydrolytic degradation of polyarylate was investigated at 100°C. The equilibrium water sorption in weight percent, C∞, was determined to be C∞ = 0.0043 X (RH)1.2. For specimens 0.32 cm thick, it takes about 24 h to reach 0....
