Different solution properties like viscosities, conductance, surface tension and light scattering of poly(ethylene oxide) dissolved in water, in the absence as well as presence of some salts like LiCI, NaCI and KCI have been studied over a wide range of polymer concentration. The data so obtained are analyzed and correlated/discussed in the light of conformational changes with the change in ionic strength and ionic size of the electrolytes used. From the initial data of conductance, the limiting conductance and. other related parameters have been obtained. From these results, the degree of association (a.), association constant (k.) of the polymer and effect of different parameters upon these are discussed. From the results, we can conclude that degree of association and association constant of polyelectrolytes can also be estimated through conductance measurement.
