Abstract
Expressions are derived for the osmotic pressure and turbidity of a dilute solution of two chemically dissimilar polymer species in a solvent. The relations obtained are contrasted with those derived through use of the free energy of mixing as given by the quasi‐crystalline lattice model. Use of equations based on the lattice model to evaluate polymer‐polymer interaction parameters from dilute solution data is shown to be valid only in special instances.Keywords
