Y. Yampolskii et al., Novel correlation for solubility of cases in polymers: Effect of molecularsurface area of cases, J APPL POLY, 76(4), 2000, pp. 552-560
Novel correlations are proposed for the solubility coefficients of gases (S
) as well as the parameters of the dual mode sorption isotherms k(D) and b
in polymers. They are based on the concept of molecular surface areas of di
ssolved species. Van der Waals surface areas (WSA) as estimated using UNIFA
C group contributions and solvent accessible surface areas (SASA) were cons
idered as possible parameters for correlations. Excellent dependencies with
correlation coefficients R in the range 0.95-0.99 were obtained for the co
rrelations of ln S, ln k(D), and ln b with surface area. (C) 2000 John Wile
