Acoustic and viscometric studies of solutions of polystyrene and high-impact polystyrene in benzene, toluene, and tetrahydrofuran

Ultrasonic measurements of Polystyrene (PS) and high‐impact polystyrene (HIPS) solutions in benzene, toluene, and tetrahydrofuran are reported at 2‐MHz frequency. Effect of solvent and the rubbery phase of HIPS on the ultrasonic measurements are discussed. Observed relaxation times demonstrate the i...

Zusammenfassung:Ultrasonic measurements of Polystyrene (PS) and high‐impact polystyrene (HIPS) solutions in benzene, toluene, and tetrahydrofuran are reported at 2‐MHz frequency. Effect of solvent and the rubbery phase of HIPS on the ultrasonic measurements are discussed. Observed relaxation times demonstrate the interaction of polymer–polymer macromolecules and polymer–solvent molecules. Results show a linear increase of velocity, density, viscosity, absorption coefficient, relaxation time, and relaxation amplitude values with increase of PS and HIPS concentrations. In contrast as a result of interaction between polymer molecules and solvent molecules compressibility decreased with increasing polymer concentration.
