Brominated carbamoyl derivatives useful to impart flame retarding property to combustible substrates

摘要

Described are brominated carbamoyl derivatives of the structure: P P(X.sup.1) (X.sup.2) C -- CH.sub.2 -- (R.sup. 2).sub.n -- O - - C(O)N(R) (R.sup.1) (X)PP wherein: PPR and R.sup.1 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; PP R. sup.2 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) (R.sup.1);PPX, x.sup.1 and X.sup.2 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;PPProvided one of X, X.sup.1 or X. sup. 2 is a bromo or a bromo substituted alkyl; and that each carbamoyl group has a replaceable hydrogen in the R or R.sup.1 group.P P These compounds are useful to impart flame retardant property to combustible substrates.
