摘要
本文从高分子体系内分子链间相互作用能出发,得到了一个描述高聚物高压下的等温状态方程 从实验中发现n、m为普适常数,n=6.14,m=1,16.在不存在转变的情况下,该方程对处于玻璃态、结晶态及液态高聚物体系均适用.
In this paper, a new equation of state for polymers is derived theoretically. A comparison of the equation with experimental data is made for 6 polymers at different temperatures and pressures. The results obtained show that the equation of state is suitable to describe the isothermal compressing behaviour of polymers in the state without transitions.
