Miscibility on blends of PVA and PFSA by viscometry

The intrinsic viscosity and viscometric interaction parameters of perfluorosulfonic acid (PFSA) and poly(vinyl alcohol) (PVA) were measured by dilute solution viscometry. The miscibility between PFSA and PVA was estimated by the criteria of Δ B and µ. The results indicated that PFSA and PVA were com...

Summary:The intrinsic viscosity and viscometric interaction parameters of perfluorosulfonic acid (PFSA) and poly(vinyl alcohol) (PVA) were measured by dilute solution viscometry. The miscibility between PFSA and PVA was estimated by the criteria of Δ B and µ. The results indicated that PFSA and PVA were completely miscible for any weight fraction in aqueous solution.
