Thermal degradation of 2,4,6-tri[(bromo)x anilino]-1,3,5-triazines

Abstract

The need 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 400°C.
