Abstract: This study investigated the molecular interaction between polystyrene and toluene through experiments conducted at varying concentrations and two fixed temperatures. 1H NMR, 13C NMR, and IR spectroscopy were used to evaluate changes in the chemical structure of the polymer, revealing the nature of the interaction between polystyrene and toluene as concentration and temperature varied. Our results demonstrated that the abrupt changes in thermo-physical properties of polymeric solutions at characteristic temperatures and concentrations were due to structural interactions, such as polymer chain association, segmental motion, frictional force between the layers of the polymer, and hydrogen bonding. These findings contribute to a better understanding of the physiochemical behavior of polymeric solutions, which has important implications for various industries that utilize such materials.
