Abstract
The concept of a continuous lattice from the viewpoint of classical mechanics was introduced and a Lennard-Jones 6–12 potential was used to modify the lattice fiuid theory of Sanchez and Lacombe. Thus, a new equation of state for pure polymeric liquids was obtained. With this equation, PVT data, thermal expansivities and isothermal compressibilities of several polymeric liquids were calculated and compared with experimental values and with those of the lattice fluid theory and other theories. The new equation gave similar precision to Hole theory in the calculation of volume, thermal expansivity and isothermal compressibility and gave better agreement with the experimental data than the other theories used in the comparison.
