УДК 541.64 PROPERTIES AND FEATURES OF POLYMER-METAL COMPLEXES

Abstract

The main purpose of the work was to study the possibility of obtaining new polymer-metal complexes, determining their properties and practical application in catalysis. The method of potentiometric titration was used in the work. It was discovered and proved that during potentiometric titration, the complex is formed in a system of Zn²⁺ ion and polyvinylpyrrolidone. The influence of temperature on the formed complexes was studied, as well as how the viscosity changes depending on temperature, and a relationship between temperature and viscosity was found. The catalytic properties of polymer-metal complexes were studied and it was found out how effective their use as catalysts is. Chemically pure reagents were used in the work, for some additional purification was used. In the course of the work, it was proved that the method used in the experiment is very sensitive and accurate to the formation of polymer-metal complexes. The devices used are pre-configured and graded (analytical scales, pH-meter).
