Variation of the second virial coefficient as a function of polymer composition for three pairs of polystyrene mixtures in 2-butanone has been studied using static light scattering. The results are better represented by the simple method of taking the geometric mean of the second virial coefficients
## Abstract Light scattering measurements were carried out on several standard polystyrenes and their binary mixtures in benzene and in 2βbutanone. Their second virial coefficients, B~2~, were determined as a function of the polymer composition. It was revealed that for some pairs of mixtures whose
