Abstract

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.
