Новые водорастворимые функциональные сополимеры на основе 1-винил-1,2,4-триазола и аллиламина синтезированы в условиях свободно-радикального инициирования под действием динитрила азобисизомасляной кислоты. Варьированием условий реакции получены сополимеры разного состава с молекулярной массой 1287–30204 Да. Структуру, молекулярную массу и физико-химические свойства сополимеров определяли с помощью методов элементного анализа, ИК- и ЯМР 1Н-спектроскопии, гель-проникающей хроматографии, потенциометрического и турбидиметрического титрования, динамического светорассеяния, термогравиметрического анализа. Установлено, что сополимеры проявляют свойства высокоомных органических полупроводников, характеризуются удельной электрической проводимостью порядка 10-13 –10-14 См/см, обладают высокой стойкостью к термической деструкции (до 260–280 °С). Полученные сополимеры являются перспективными в качестве стабилизирующих полимерных матриц при формировании водорастворимых гибридных органо-неорганических нанокомпозитов, обладающих биологической активностью.

New water-soluble functional copolymers based on 1-vinyl-1,2,4-triazole and allylamine were synthesized under the action of free-radical initiation conditions and azobisisobutyric acid dinitrile. Сopolymers of various compositions with a molecular weight of 1287–30204 Da were obtained by varying reaction conditions. The structure, molecular weight and physicochemical properties of the copolymers were determined using elemental analysis, IR and NMR 1H-spectroscopy, gel permeation chromatography, potentiometric and turbidimetric titration, as well as dynamic light scattering and thermogravimetric analysis. It was established that the obtained copolymers, exhibiting the properties of high-resistance organic semiconductors, are characterized by a specific electrical conductivity of 10-13 – 10-14 S/cm and high resistance to thermal destruction (up to 260–280 °C). These copolymers are promising as stabilizing polymer matrices in the formation of biologically active water-soluble hybrid organic-inorganic nanocomposites.
