Doctor of sciences, professor, laureate of the State Prize of USSR, holder of “Badge of Honour” order and several medals. Deputy director of INEOS RAS (1975-1988).
Prof. Sergeev was a well-known scientist. He had carried out important investigations in many areas of polymer chemistry. In particular he studied the polymers of levoglucosan, shockproof polyamides obtained by anion-activated polymerization of caprolactam, thermoreactive polyphenylenes obtained by cyclotrimerization of alkynes and diynes, phenol-formaldehyde oligomers and polymers widely used as construction and insulation materials, carborane-containing polymers, polyphenylene sulfides and many other. Prof. Sergeev was the head of the laboratory of technology (1971-1996) and laboratory of polyarylenes (1978-1996).
