摘要: 聚苯乙烯(PS)的松弛过程有大量研究.应用热释电法(TSC)研究聚苯乙烯的松弛报道较少.

关键词: 聚苯乙烯, 松弛现象, 热释放电流谱

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
