Abstract
Abstract Halogenated aryl compounds having the formula ##STR1## WHEREIN Z is bromine or chlorine, m and m' are integers having a value of 1-5, i and i' are integers having a value of 0-2, R is herein defined, M and M' are each independent and are from the group oxygen, nitrogen or sulfur with the proviso that M and M' cannot concurrently be oxygen in both cases, and A is chlorine, cyano, nitro, lower alkoxy, lower alkyl, fluorine, dialkylamino, phenyl, halo-phenyl, benzyl, or halo-benzyl, and which compounds are found useful as flame retardants for various polymeric systems.
