THE INFLUENCE OF ACIDITY OF THE ENVIRONMENT ON STRUCTURAL CHANGES AFTER SYNTHESIS IN THE OLIGOMERS ON THE BASIS OF MONTHMORILLONITE AND OLIGOPHENYLENE

Abstract

The effect of montmorillonite on the structure of phenylene-based oligomer was studied. The influence of the pH of the reaction medium on the formation of the structure of the obtained composite oligomer was studied. It is shown that an increase in the concentration of the alkaline solution of the initial oligophenylene leads to an increase in the molecular weight of the organic fragments of the oligomer. While this process, the exfoliation of montmorillonite into the constituent aluminosilicate packets is occured. A mechanism was also proposed for the formation of additional bonds of the –Si – O – C– type between the phenylene and aluminosilicate fragments. These assumptions are proposed with the results of IR spectroscopy.
