Abstract

The intensity of light scattered from dilute solutions of mixtures of two nonidentical polymers in a single solvent was measured. The parameter A~24~ characterising the thermo‐dynamic interaction of two nonidentical polymer molecules in solution was calculated for several systems polymer 2 ‐ polymer 4 ‐ solvent. For chemically strongly different polymers, A~24~ is independent of molecular weights of the polymers and probably also of solvent. A~24~ is related to the compatibility of both polymers and decreases contrary to expectation with increasing chemical difference between polymers 2 and 4.
