Abstract: Electrochemical properties of mutual activation of polymers as a result of remote interaction of interpolymer system KU-2-8:AV-17-8 have been studied. Interpolymer systems consisting of polymers cationite: anionite KU-2-8 and AV-17-8 were chosen as objects of study. As a result of remote interaction, mutual activation of ion-exchangers occurs, as a result of which polymers pass to the state of high ionization, significantly changing the electrochemical properties of solutions, such as conductivity and pH. The purpose of the study is to investigate the features of mutual activation of interpolymer systems KU-2-8:AV-17-8. The obtained results as the value of specific conductivity of aqueous medium in 5:1 ratio gradually increased after 24 hours. It was noted that the pH value of the medium in this ratio gradually decreases, and the swelling coefficient of the anionite AV-17-8 increased to a maximum value of 3.86 after 1 hour at a ratio of 5:1 in the presence of the cationite KU-2-8. In the ratios of the interpolymer systems KU-2-8: AV-17-8 4:2, the specific electrical conductivity of the aqueous medium after 6 hours reaches a maximum value of 7.0, and the pH indicator decreases compared to the initial value. The value of electrical conductivity gradually increases in the ratios 2:4 and 1:5 in different time intervals. At 2.5 hours of the study, it can be observed that the pH of the medium decreased from a maximum value of 7.45 to a minimum value of 4.85 at ratios of 3:3 and 2:4. The swelling ratio at 2:4 ratio increased after 2.5 hours and decreased after 6 hours. Conclusion. As a result of remote interaction, changes in electrochemical properties of polymers of cationite KU-2-8 and anionite AV-17-8 are observed in all molar ratios. Remote interaction has a special influence on the electrochemical properties of the environment. The experimental results obtained show that changing the initial state of one component changes the electrochemical behavior of ionites and interpolymer systems.
