Counterion dissociation dependence of chain conformation for poly(xylylene tetrahydrothiophenium chloride) in semidilute aqueous solution

To further reduce the counterion dissociation from PXT in the aqueous solution, a sodium chloride external salt was explored. With f estimated by the modified Manning theory, in particular for the salt-containing polyelectrolyte¹¹ and v estimated from the plots of reduced viscosity vs segmental concentration, the relationship between v and f was then established.
