Paper Abstract

Using differential scanning calorimetry we study aging phenomenon, i.e. the out ofequilibrium evolution ofthe molecular compound 2-biphenylmethanol quenched into a glassy state, namely, the variations of the entropy at the glass transition on the waiting time after quench, and preparation (cooling rate) method was studied. It was found that variation of the entropy start being appreciable for the time spent in the glassy state more than 60 mm and is essentially constant for t <60 mm. It has also been studied kinetics of the glass transition at different cooling/heating rates, and has been found that there is a hysteresis effect in the temperature variation ofthe heat flow.
