Dilute solution viscometry experiments have been carried out in five ternary polymer systems solvent(1)/polymer(2)/polymer(3). Values of the specific viscosity of polymer (3) in a ‘binary solvent’ formed by polymer(2) + solvent(1) have been used to determine the compatibility of the polymer blends. Krigbaum and Wall formalism has been used to predict compatibility which relies on an interaction parameter $b_{23}^{(1)}$ that depends on the concentration, weight fraction and molar mass of each polymer. To reduce the dependences and to clarify the criterion of compatibility, a parameter $b_{23}^{(2)}$ independent of polymer (3) composition and molar mass has been deduced. This parameter shows the same behaviour with polymer(2) concentration as the Stockmayer–Fixman parameter B . © 2001 Society of Chemical Industry
