## Abstract **Summary:** Theoretical analysis of the possibility of collapse/swelling phase transition propagation along a polyelectrolyte gel thread has been performed. A differential equation that determines the time dependence of the degree of swelling of polymer thread under the radial mechanic
The sensitive response of weak-acid ion exchangers to counterion concentrations in the aqueous phase has been attributed to a Donnan potential term. By correcting for this term a constant pK a has, in a number of cases, been resolved for the repeating unit at each point of their titration with base.
The influence of counterion radius on the polyelectrolyte behavior of poly-kcysteate in aqiieous solution under different conditions was investigated. A h e a r relationship was found between a critical concentration in solution of the synthetic charged polypeptide and the crystallographic radius of
