Abstract
The parameter [MATH] which is characteristic of melts, liquids and polymers, has also been shown to be characteristic of polymer solutions. Calculated data, using the volume expansivity of the polymer solution, establish the constancy of the [MATH]-parameter which retains, on an average, a constant value of 1.11 in polymer solutions. The parameter [MATH] has also been shown to be related to the anharmonic Gruneisen parameter, fractional free (available) volume, solubility parameter and Flory - Huggins interaction parameter [MATH] in dilute polymer solutions. The results have been used to develop further understanding of the significance of fractional available volume and the [MATH]-parameter in describing various thermo-acoustic properties and the anharmonic behaviour in polymer solutions.
