| Abstract: | Viscosities of a
few cationic polyelectrolytes possessing N-alkyl/N-acyl ammonium and 2,5-thiophenylene
linkages in their respective repeating units of the chain (mol. wt. 1154-3815)
have been studied in two dipolar aprotic solvents, viz. propylene carbonate
(PC) and sulpholane. The results are treated on the basis of Fuoss-Strauss
equation. The intrinsic viscosities obtained from Fuoss-Strauss equation, in conjunction
with the derived parameters such as characteristic ratio (C∞), maximum
cross-dimension ( ), root mean square end-to-end distance (< Rg2
>1/2) and plane projection distance (P) are invoked to comprehend
polycationic hydrodynamic models in both solvents. |
