摘要：
On the basis of concentration pH dependences of binary solutions of anionic polyelectrolyte, polymethacrylic acid, and nonionic surfactant, nonylphenoxypoly(ethoxy)ethanol the role of hydrophobic interaction in the development of associative and aggregative processes was shown. It is established that the criterion of evaluation of the preferred contribution of hydrophobic interaction is the inflection point on the dependence of pH difference of the individual solutions of nonylphenoxypoly(ethoxy)ethanol and binary solutions of polymethacrylic acid and nonylphenoxypoly(ehoxy)ethanol on the logarithm of ratio of their concentrations.
