Use of inverse gas chromatography for the investigation of polymer‐polymer interactions is compromised by a dependence of the measured polymer‐polymer interaction coefficient, B 23 , on the chemical nature of the probe in contradiction to theory currently used. We have developed a procedure whereby the “true” B 23 , may be extracted from the probe dependent data. Additionally a theory of mixing based on a multidimensional solubility parameter approach has been developed. The new theory has been used to predict the polymer‐polymer interaction coefficients and these are compared with experimentally determined values on several miscible blends.
