for more efficient and 'greener' flame retardants for polymeric
materials is ever present and of increasing intensity as regulatory agencies
continue to display concern about the environmental impact of traditional
materials. Compounds capable of multiple modes of action would be particularly
desirable. Compounds containing both bromine (for good gas-phase activity)
and nitrogen (to promote solid-phase activity) should be good candidates for
development as flame retardant agents. A series of 2,4,6-tri[(bromo)xanilino]-1,3,5-triazines
have been synthesized and characterized spectroscopically. The degradation
characteristics of these compounds have been examined using thermogravimetry.
They undergo step-wise decomposition beginning at about 400C.
