“…Recently, interpolymer complexes stabilized by bonds that differ from Coulomb bonds, such as hydrogen and ion-dipole bonds [1,2], have been of great interest, since they can be used as pH-and temperature-responsive components in the development of microcapsules, nanoparticles, and controlled release hydrogels, as well as polymer electrolyte membranes [3]. Complexes stabilized by hydrogen bonds are formed between polymers having a proton donor (usually polyacids) and a nonionic polymer containing a strong hydrogen acceptor in the backbone.…”

Complexation in aqueous salt-free semidilute solutions of poly(styrenesulfonic acid) and poly(ethylene oxide) leading to the formation of soluble poly(styrenesulfonic acid)–poly(ethylene oxide) complexes is studied. It is shown that the interaction of the components in such complexes significantly weakens with an increase in temperature, as well as with a decrease in the poly(ethylene oxide) chain length. Using viscometry and light scattering, it is demonstrated that, in dilute aqueous and aqueous-saline solutions, no complexes are formed between poly(styrenesulfonic acid) and poly(ethylene oxide) and the system is a compatible mixture of the polymers in a common solvent.

“…Among the techniques used to evaluate the compatibility of polymer blends,3 dilute solution viscometry continues to be an attractive and useful method because of its simplicity and low cost 4–10. It is based on the determination of a parameter Δ b 4, 5, 9 coming from the difference between experimental and theoretical contributions arising from interactions between the chainlike and/or unlike segments of both polymers.…”

The influence of solvent on the compatibility behaviour of Arocy B10, a cyanate ester monomer, and polysulfone (PSF) was investigated by means of dilute solution viscometry and of the preferential solvation parameter at 25 • C. The ternary systems under study are: tetrahydrofuran/Arocy B10/polysulfone (PSF), N,N-dimethylformamide/Arocy B10/PSF and dichloromethane/Arocy B10/PSF. Values of the specific viscosity of PSF in a 'binary solvent' formed by Arocy B10 + solvent have been used to determine the compatibility of the polymer blend Arocy B10/PSF. An interaction parameter b that depends on concentration has been determined. The preferential solvation parameter was measured by size-exclusion chromatography at different monomer-to-polymer ratios. PSF was found to be preferentially solvated by the monomer. Both techniques agree quantitatively in every system indicating maximum compatibility at the same Arocy B10 concentration. However, they differ when comparing the two parameters among the three systems.

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
