ABSTRACT:
Disclosed are novel compounds of the formula: ##STR1## WHEREIN EACH Z is independently selected from the group consisting of hydrogen and halogen; Y is oxygen or sulfur; n is an integer of from 1 to 3; a, b, and c are integers of from 0 to 1; n+a+b+c=4; and wherein X, X', X" are independently selected from the group consisting of hydrogen, halogen, alkyl of 1 to about 8 carbon atoms and --OC(O)R, provided that at least one of said X, X', X" substituents is --OC(O)R, and R is independently selected from the group consisting of alkyl of 1 to about 18 carbon atoms, haloalkyl of 1 to about 18 carbon atoms, alkoxyalkyl of from 1 to about 18 carbon atoms, aryl of from 6 to about 18 carbon atoms, and haloaryl of from about 6 to about 18 carbon atoms.
The above compounds may be topically applied to polyester-containing textile materials in order to flame retard them; and the materials so treated have a durable flame retardance.
