Abstract
The original van Laar's theory has been modified, The internal pressures of components and mixture are expressed by Frank's relation and the excess en tropy for mixing of components is also considered. A. new activity coeffici ent equation, which can be satisfactorily applied to polymer solutions, is obtained. The calculated results for the VLE of 179 polymer solutions show that the accuracy of fit is evidently superior to UNIQUAC equation.
