M. Banaszak et al., THERMODYNAMIC PERTURBATION-THEORY - STICKY CHAINS AND SQUARE-WELL CHAINS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 48(5), 1993, pp. 3760-3765
We extend Wertheim's first-order thermodynamic perturbation theory [J.
Chem. Phys. 87, 7323 (1987)] to sticky chains and square-well chains.
The predicted compressibility factors for square-well chains are foun
d to agree with Monte Carlo data. We demonstrate that the effect of ch
ain connectivity is to reduce the attraction contributions to the comp
ressibility factor and to the critical temperatures.
