The work is devoted to the synthesis of poly-(N-phenylenbenzimidazoles), poly(benzodiimidazoles) and the production of nanofiber materials based on them. The relevance of the work is due to the fact that nanofibers obtained from polymer can be used to cover wound dressings. Bisbenzymidazoles are being developed as agents that bind small DNA grooves with antitumor activity, and can act as ligands to transition metals for modeling biological systems.

The synthesis of poly(D,L-lactide) with a predetermined molecular weight ranging from 5 to 143 kDa was conducted by ringopening polymerization of lactide in the presence of varying concentrations of the 1,12-dodecanediol activator. To synthesize poly(D,L-lactide) with COOH-end groups, polymerization was carried out in the presence of L-lactic acid. The synthesised polymer was found to contain an order of magnitude higher concentration of COOH groups than poly(D,L-lactide) synthesised in the presence of 1,12-dodecanediol.

A method for obtaining an unsaturated polyester resin based on recycled polyethylene terephthalate has been developed. The process of curing an unsaturated polyester resin under the action of styrene, a peroxide compound (Butanox 50M) and an accelerator (cobalt stearate and dimethylaniline) has been studied. The physical and mechanical properties of polymeric materials based on the developed resin have been studied. It has been established that their strength depends on the mass fraction of recycled polyethylene terephthalate in the oligoether polyol used in the synthesis.

A comparative analysis of a magnesium-zinc stabilizer based on pentaerythritol and a standard calcium-zinc stabilizer based on stearic acid was carried out. The influence of the ratio of pentaerythritol magnesium (PenMg) to pentaerythritol zinc (PenZn) on the thermal and thermo-mechanical stability of polyvinyl chloride (PVC) is considered.

Filling compositions based on epoxy-diane resin have been developed, the curing process using polyesteramides has been investigated, and the activation energies of the curing reaction have been calculated. The effect of increasing the amount of PET on the thermal characteristics and physico-mechanical properties of filling compositions is shown. The test results show that the filling compositions obtained using the developed polyesteramides are superior in properties to compositions based on industrial amine hardeners.
