Thermo-viscous investigations of molecular interactions for the binary mixtures of polyethylene glycol-400 and polyethylene glycol-600 with dimethyl sulfoxide and water at different temperatures

Thermo-viscous investigations of molecular interactions for the binary mixtures of polyethylene glycol-400 + dimethyl sulfoxide and polyethylene glycol-600 + water has been done within the temperature range 298.15 K to 308.15 K. Several thermo-dynamical parameters such as Moelwyn-Hughes parameter, Beyer's non-linear parameter, Lattice Gruneisen parameter, Sharma's constant, Excess Gibbs free energy of activation, and Gruenberg-Nissan interaction...
