In this work, Henry's Law constants of nonpolar solutes in four polymers were obtained by extrapolation of finite concentration vapor-liquid equilibrium (VLE) data using the UNIQUAC equation to infinite dilution condition. The consistency of the results was confirmed by comparing them with infinite dilution data through the linear relationship between logarithm of Henry's Law constants and inverse of temperatures. This verification provided good method for crosschecking a reliability of finite concentration VLE data with infinite dilution data. Henry's Law constants were correlated based on both types of data as a function of temperature using the classical van't Hoff equation. Generalized correlations of the Henry's Law constants of solutes were proposed for polyisoprene (PI), polyisobutylene (PIB) and poly(n-butyl methacrylate) (PBMA).
