Viscosity is a measure of the resistance for a fluid to flow and it is affected by several factors including concentration and temperature. In the present study, an attempt has been made to compute the activation energy and to analyse the molecular interactions of Polyethylene Glycol (PEG) 2000 in toluene at different concentrations at different temperatures (303 K, 308 K 313 K, 318 K) by determining relative viscosity, ultrasonic velocity and density. Various parameters like adiabatic compressibility, free volume, internal pressure etc., are calculated at 303 K and the results are discussed in the light of polymer-solvent interaction. This work helps to understand the behavior of macromolecules with respect to changing concentration and temperature. Also, viscosity and activation energy (Q) results are correlated to understand the increased entanglement of the polymer chains due to the increase in the concentration of a polymer solution that leads to a decrease in the viscosity and activation energy of viscous flow.
