The influence of counterion radius on the polyelectrolyte behavior of poly‐ L ‐cysteate in aqueous solution under different conditions was investigated. A linear relationship was found between a critical concentration in solution of the synthetic charged poly‐peptide and the crystallographic radius of different counterions, indicating that the stability of this macromolecule is inversely proportional to the size of the cations.
