Abstract

The properties of solutions of regular hydrophobic polyampholytes in the presence of a low-molecular-mass salts were studied by means of stochastic dynamics. The temperature dependence of the chain size at different concentrations of the supporting electrolyte was considered. As the temperature increases, the growth of the polyampholyte chain in size becomes faster in the system that contains the supporting electrolyte; however, a contraction of the chains takes place in the presence of the salt relative to the salt-free solution at high temperatures.
