Abstract: The relaxation temperatures of polystyrene were measured by thermally stimulated current method.The influence of storage time of sample,sample thickness,number ofpolarization cycles and velocity of temperature rise on the relaxation were studied and the activation energy of relaxation was calculated.

Key words: polystyrene, relaxation phenomenon, thermally stimulated current spectrum
