采用先前发表的聚合物非弹性变形的理论方法，分析了聚苯乙烯和聚苯乙烯与聚二甲基苯氧基苯醚的均匀共混物的动态力学测量数据。无论是等温实验还是等时实验，理论曲线和实验曲线都得到了令人满意的吻合。文中分别得到了理论中涉及的参数，并强调了它们的物理意义。
A theoretical approach for the non-elastic deformation of polymers, previously published, was used in order to analyze data obtained by dynamic mechanical measurements with polystyrene and homogeneous blends of polystyrene and poly (dimethyl phenylene oxide). A satisfactory agreement has been observed between theoretical and experimental curves for both isothermal and isochronal experiments. The parameters involved in the theory are obtained separately and their physical meaning is underlined.
