| 中文摘要 | the developments of physical aging in phenolphthalein poly(aryl-ether-ketone) (pek-c) and poly(aryl-ether-sulfone) (pes-c) with time at two aging temperatures up to 20 k below their respective glass transition temperatures (t-g = 495 and 520 k) have been studied using differential scanning calorimetry (dsc). substantial relaxation within the aging course of several hours were observed by detecting t-g decreasing during physical aging process at the two aging temperatures. the relaxation processes of both polymers are extremely nonlinear and self-retarding. the time dependencies of their enthalpies during the initial stages of annealing were approximately modeled using the narayanaswamy-tool model. the structure relaxation parameters obtained from this fitting were used to predict the possibility of physical aging occurring at their respective using temperatures.
