| 摘 要： | 关于液态、玻璃态和固态高聚物系统以及小分子固态物质的等温态方程,大多是用零压及零压下的积为参量,这显然影响方程应用的普遍性 精确性。为此,导出了一个改进的高压下高聚物系统的等温态方程,它可以任意选择某一压强以及该压强下的体积和体积弹性模量?参量,计算和描述高压下高聚物系统等温压缩行为。

| Abstract: | Although most of the equations of state for polymers and low molecular substances have chosen the volume at zero pressure as a parameter, we propose a new equation of atate for polymer solids and liquids, which removes this restriction. The new equation of state allows one to choose any pressure and volume at this pressure as parameters to predict the compressibilities of polymer systems. Using this approach, we also show that the scaled relationship provided by Sanchez et al is identical to ours at low pressure. |
