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

The blending of polymers is one of the simplest means to obtain a variety of physical and chemical properties from the constituent polymers [1]. A simple method to analyzepolymer-polymer miscibility in solution is the viscometric technique [2]. The viscosity study on ternary system of twodifferent polymers and a solvent has been a subject ofcontinuing interest, mainly due to its simplicity and importance in the characterization of the intermolecularinteraction between the two different polymers in solution [3]. The conformation of the polymer chain in solution can be affected the thermodynamic parameters and hydrodynamicparameters; therefore compatibility of polymer can be explained in terms of the thermodynamic and hydrodynamic parameters
