В результате проведенной работы были получены фосфазенсодержащие бензоксазиновые соединения на основе диаминов различного строения. Полученные соединения охарактеризованы методами 1Н ЯМР спектроскопии, изучены термические и реологические свойства для бензоксазинов на основе диаминов, а также представлены данные по горючести. Исследовано влияние структуры исходного диамина на свойства получаемого мономера и полимера. Изучена кинетика отверждения композиций бензоксазинов с разным содержанием фосфорсодержащих катализаторов-антипиренов на основе гексахлорциклотрифосфазена и м-толуидина. Синтезированные мономеры и полученные композиции бензоксазинов с катализаторами-антипиренами могут быть использованы в качестве термо- и огнестойких связующих для полимерных композиционных материалов, а также в качестве отвердителей для эпоксидных смол.

Phosphazene-containing benzoxazine compounds based on diamines of various structures were obtained as a result of the work performed. The resulting compounds were characterized by 1H NMR spectroscopy, the thermal and rheological properties of benzoxazines based on diamines were studied, and data of flammability were presented. The effect of the structure of the initial diamine on the properties of the resulting monomer and polymer has been studied. The curing kinetics of compositions of benzoxazines with different contents of phosphorus-containing flame retardant catalysts based on hexachlorocyclotriphosphazene and m-toluidine was studied. The synthesized monomers and the resulting compositions of benzoxazines with flame retardant catalysts can be used as heat and fire resistant binders for polymer composite materials, as well as hardeners for epoxy resins.
