INFLUENCE OF THE EFFECT OF REMOTE INTERACTION OF THE INTERPOLYMER SYSTEM KU-2-8:AV-17-8

Abstract

Abstract. Introduction. 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.
