modeling the transport and volumetric properties of solutions containing polymer and electrolyte with new model

A new theoritical model based on the local composition concept (tnrf-mnrtl model) was proposed to express the short-range contribution of the excess gibbs energy for the solutions containing polymer and electrolyte. this contribution of interaction along with the long-range contribution of interaction (pitzer-debye-hückel equation), configurational entropy of mixing (flory-huggins relation) and eyring absolute rate theory were used to fit the viscosity values of ternary aqueous solutions of polymer + electrolyte with considering temperature dependency. the local composition models which are available for correlating the thermodynamic properties of ternary polymer + electrolyte solutions (ternary-wilson, ternary-modified nrtl, and ternarymodified wilson) with eyring absolute rate theory were also used for fitting the viscosity values of ternary solutions for the first time. the fitting quality of eyring-tnrf-mnrtl model was compared with these models. the equations of apparent molar volume were also derived from tnrf-mnrtl, ternary-wilson, ternary-modified nrtl, and ternary-modified wilson models. these equations were used for correlating the apparent molar volume and density values of ternary polymer + electrolyte solutions.
