ABSTRACT Described are brominated carbamoyl derivatives of the structure: (X) (X1) (X2) C - CH2 - (R2)n - O - C(O)N(R) (R1) wherein: R and R1 independently selected from the group consisting of hydrogen, alkyl, alkanol, cycloalkyl of from 5 to 7 carbon atoms, phenyl, alkyl substituted by phenyl, phenyl substituted by alkyl, hydroxy terminated oxyalkylene, hydroxy substituted hydroxy terminated oxyalkylene and halogen substituted hydroxy terminated oxyalkylene; R2 is independently selected from the group consisting of alkylene, oxyalkylene, hydroxy substituted oxyalkylene, halogen substituted oxyalkylene and alkylene or oxyalkylene substituted by the group - O - C(O)N(R) (R1); X, X1 and X2 are independently selected from the group consisting of halogen and halogen substituted alkyl, wherein the halogen is chlorine or bromine; said alkyl, alkanol and alkylene each independently has from 1 to 4 carbon atoms; said oxyalkylene having from 2 to 4 carbon atoms; n is 0 to 20; preferably 0 to 6; provided one of X, X1 or x2 is a bromo or 2 bromo sub- stituted alkyl; and that each carbamoyl group has a replaceable hydrogen in the R or R1 group. These compounds are useful to impart flame retardant property to combustible substrates.
