Abstract

Abstract: Oxidative polymerization of aniline and 2‐(2‐chloro‐1‐methylbut‐2‐en‐1‐yl)aniline gave corresponding hitherto unknown copolymers with various compositions. The copolymers were studied by several techniques, including UV–visible spectroscopy, Fourier transform IR spectroscopy, cyclic voltammetry, thermal analysis and SEM. Copolymerization of aniline with an ortho‐substituted aniline derivative leads to the appearance of luminescence whose intensity increases with growth in the content of the substituted monomer units. It has been shown that the solubility of the copolymers obtained is determined by their composition. It has been found that the temperature of the start of thermal destruction of the copolymers increases with an increase in the content of a functionalized monomeric aniline therein. The solubility of the copolymers makes it possible to create homogeneous thin films and use them as the active layer in resistive gas sensors. © 2022 Society of Industrial Chemistry.
