Viscometric study on the compatibility of poly(vinyl acetate)-poly(vinyl pyrrolidone) in solution

A simple method to analyze polymer-polymer miscibility in solution is the viscometric technique [۱]. The viscosity study on ternary system of two different polymers and a solvent has been a subject of continuing interest, mainly due to its simplicity and importance in the characterization of the intermolecular interaction between the two different polymers in solution [۲]. Compatibility of polymer can be explained in terms of the thermodynamic and hydrodynamic parameters [۳].
