The Effect of Ionic Liquid On The Intrinsic Viscosity of Aqueous Polyvinyl pyrrolidone Solutions

The wide use of polymers in many fields emphasizes the need to analyze different polymer-solvent interactions. In a good solvent, polymer coils swell and expand, whereas in marginalsolvent conditions, they contract to their unperturbed dimensions. Addition of another solvent in a polymer solutioncan greatly enhance or reduce the polymer miscibility [1,2]. Room temperature ionic liquids (IL) have emerged as new class of solvents for practical application due to their uniqueproperties. The use of ionic liquids in polymer science is not limited to their applications as solvents. Ionic liquids are used as additives to polymers(plasticizer, components of polymer electrolytes) [3].
