Abstract

Various acoustical Parameters of Poly (4, 4'-Cyclopentylidene diphenylene toluene - 2,4-disulfonate) (PSBT) in Chloroform, 1-2-dichloroethane, 1,4-dioxane and tetra hydrofuran were evaluated at 30< sub>0 C using an interferometer operating at a frequency of 3 MHz. Some of these parameters, except the internal pressure, relaxation time, classical absorption coefficient and solvation number, were correlated with concentration. Excellent linear correlations between the parameters U, Z, KS, R, b, Lf and nand concentration are observed.
