Hexahydrotriazine (HT) materials and hemiaminal (HA) materials derived from aromatic, aliphatic, and/or polyether diamines may he used as a platform for creating flame retardant materials. Various flame retardant material precursors may he incorporated into the HA and HT materials. Examples of flame retardant precursors may include organohalogen materials, organophosphorous materials, malamines, and dianiline compounds, among others. The flame retardant materials and precursors may he single molecule species, oligomers, and/or polymers (i.e., polyhexahydrotriazine, PHT, polyhemiaminal, PHA). The flame retardant materials may he made using an aromatic diamine, an aliphatic diamine, a polyether diamine, or a mixture thereof to react with an aldehyde (i.e. formaldehyde or paraformaldehyde). Such flame retardant material precursors will complex with the diamine monomers via a copolymerization reaction to form the flame retardant materials. |
