Solvation Study Of Polyvinylidene Fluoride In N-N Dimethylformamide Through Padova And Shiio Model

Ultrasonic velocity and density measurements for the solutions of polyvinylidene fluoride in N-N dimethyl formamide have been made as a function of concentration and temperature. The data are used to compute the solvation number using the methodology based on Padova model and shiio model. Using solvation number, the parameters like apparent molar compressibility, apparent molal volume and molar solvated volume are estimated in both the models and compared with those values obtained by the traditional method.
