In this work we discuss the results of obtaining new high-sulfur polymers based on pyrrole and elemental sulfur. For the synthesis of high-sulfur based on pyrrole polymers was used method of co-oxidation of pyrrole and polysulfone, previously generated in situ from an aqueous solution of sodium polysulphide in the presence of H₂O₂/FeCl₃/HCl oxidation system. Depending on the reaction conditions, the addition of reaction mixture of gelatin or surfactant, sulfur-pyrrole polymers with a high sulfur content were obtained: from 75.2 to 87.9%. The conditions for carrying out the reaction are selected, which allow varying the sulfur content in obtained copolymers. The physico-chemical properties and microstructures of the obtained copolymers were studied. It is established that the synthesized copolymers have thermal stability, semiconducting properties, have a developed microstructure, with sufficiently small microparticles of narrow polydispersity and are promising for the development of active cathode materials of modern rechargeable lithium current sources.
