Redox polymers based on polyamines

Abstract

Conditions of formation of redox polymers based on quinones were studied. The ways of synthesis of macromolecules containing primary amino group via nitration and reduction of polymers, chemical modification and polymerization are discussed. Some pecularities of reduction of nitrated high molecular compounds in comparison with low molecular weight analogs were established. The effect of the polymer matrix on the reactivity of the amino group in nucleophilic substitution has been studied. The ways of increasing the activity of the primary amino group in the initial polyamines by changing the substituent are discussed, as well as the effect of the type of quinoid compound on the yield and properties of polymers formed. Polyaminoquinones were used for the preparation of ion-selective film electrodes without an inner liquid compartment. The redox polymer provided thermodynamic reversibility on the membrane-electron conductor interface. As a result a stable functioning ion-selective electrode with an inner contact has been prepared.
