Abstract

Abstract Brominated carbamoyl derivatives of the structure: R.sub.2 N -- C(O) --O--(R.sup.1).sub.n -- CH.sub.2 --C (X).sub.2 --CH.sub.2 -- (R 1 ) n --O--C(O)NR 2 wherein: R is 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; R 1 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)NR 2 ; X is 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 is a bromo or a bromo substituted alkyl; and that each carbamoyl group has a replaceable hydrogen in the R group. These compounds are useful to impart flame retardent property to combustible substrates.
