The process of oxidative dehydropolycondensation of aniline on the surface of rubber crumb was studied at different ratios of components in the synthesis conditions. It was established that polyaniline is formed as a result of boundary polymerization on the surface of the substrate, is present in the composite material in the form of emeraldine salt in an amount of from 14.5 to 77.3 wt.%. The resulting structure is recommended as a sorbent for extracting metal ions of variable valence from liquid media.
