ОЛІГОЕТЕРГУАНІДИНІЄВІ КОМПЛЕКСИ ЗІ СРІБЛОМ НА ОСНОВІ АЛКІЛЗАМІСНИХ ОЛІГОМЕРІВ

Synthesized oligoetherguanidinium complexes with silver based on aromatic guanidinium oligomer and alkyl-substituted oligomers by the reaction of guanidinium-containing oligomer with silver nitrate at a molar ratio of components 1:1 in dimethylformamide at room temperature.Complexies of guanidinium-containing aromatic, aliphatic oligomers and aliphatic alkyl-substituted guanidinium-containing oligomers with silver nitrate exhibited antimicrobial activity against soil heterotrophic bacteria-destructors of protective coatings. The diameter of the zones of bacterial growth inhibition was 11-29 mm. Complexes of aliphatic alkyl-substituted guanidinium-containing oligomers exhibited greater antimicrobial activity against the studied bacteria than the guanidinium-containing aromatic oligomer. It was found that the antimicrobial activity of oligoetherguanidinium compositions depends on the length of the alkyl radical. The highest inhibition of bacterial growth was observed under the action of a complex of guanidinium oligomers with Alk-C7H15 Alk-C10H15 with silver.
