Abstract
Dielectric techniques were used to investigate the thermal expansivity of p olystyrene films. Capacitive scanning dilatometry (CSD) employs temperature ramping in order to monitor the non-linear structural relaxation in the gl ass transformation range and to quantify liquid fragility. In the linear re sponse regime, the complex thermal expansivity is obtained as a function of the temperature cycling frequency and is observed to reflect the structura l relaxation.
