| dc.description.abstract | Polymer-Polymer interaction parameters from a water soluble polymer-blend solution have been determined by viscometry at 25°C. The ternary system assayed is distilled water poly (N-vinyl-2-pyrrolidone) (PVP)/Poly (vinyl alcohol) (PVA). The intrinsic viscosity and the viscometric interaction parameters have been determined for the water/PVP/PVA ternary system. Experimental results obey the Huggins equation. Degree of miscibility of this ternary system was estimated on the basis of the signs of △Kexp , (kappa) and the value of K₁₂ a dimensionless quantity. The positive values of △Kexp and , and the higher values of K₁₂than KH value of the individual polymers reveals the miscibility of PVP/PVA blends. | en_US |
