In order to perform the polymerization process, it is necessary to measure viscosity.

The propagation of ultrasonic waves and the measurement of their viscosity in solution form an important tool for the evaluation of various acoustical and thermo-dynamical parameters which give an insight into the nature of miscibility/compatibility and molecular interactions in polymer solution. The phenomenon polymer-solvent miscibility may arises due to any specific molecular interactions such as hydrogen bonding, dipole- dipole interactions and charge transfer complexes for homogeneous polymer- solvent mixture. Miscibility is an important phenomenon in polymer solution to achieve mechanical integrity, better adhesion and better processing. In present research work we have chosen polyacrylamide solution as a highly viscous fluid.

Abstract


In order to perform the polymerization process, it is necessary to measure viscosity. In case of highly viscous fluid, viscosity starts to be dependent of the vibration and rotation frequency of the sensing element.The ultrasonic technique provides an effective and reliable tool to investigate properties of polymer solutions in the light of phase separation studies. The propagation of ultrasonic waves and the measurement of their viscosity in solution form an important tool for the evaluation of various acoustical and thermo-dynamical parameters which give an insight into the nature of miscibility/compatibility and molecular interactions in polymer solution. The phenomenon polymer-solvent miscibility may arises due to any specific molecular interactions such as hydrogen bonding, dipole- dipole interactions and charge transfer complexes for homogeneous polymer- solvent mixture. Miscibility is an important phenomenon in polymer solution to achieve mechanical integrity, better adhesion and better processing. In present research work we have chosen polyacrylamide solution as a highly viscous fluid.
