摘要：

Generalized van der Waals theory is used to obtain a three-parameter cubic equation of state which is applicable to fluids containing small or large molecules, including polymers. The necessary parameters are obtained from a minimum of experimental information. Upon extension to mixtures, the equation of state is used to calculate high-pressure phase equilibria for the ethylene-polyethylene system. The relatively simple equation may be useful for engineering-design calculations for fluid mixtures containing polymers, especially when very few experimental data are available.
