  • Online:1992-08-15 Published:1992-08-15

本文从理论上导出了一个新的三参数固态高聚物的状态方程, 在不发生转变的温度区域内, 它适用于描述固态高聚物的压强-体积-温度关系。方程形式简单, 物理参数的意义较明确。

关键词: 状态方程, 固态高聚物

A new equation of state for polymer solids was presented as P = B0/4.98[(V0/V)7.14 - (V0/V)2.16 + T/T0] (where P= pressure, V=vol., T=temp., V0= vol. at absolute zero temperature T0 and P0 pressure = 0). The equation was suitable for describing the compression behavior of solid polymers in the region without transition.(

Key words: EQUATIONS OF STATES
