Title: Flame retarding compounds

Abstract: Novel flame retarding compounds that comprise at least one sterically hindered nitroxyl, hydroxylamine or hydrocarbyloxyamine moiety and at least one conventional organohalogen or organophosphorus flame retardant moiety, represented by ##STR1## where HA is independently of each other a sterically hindered nitroxyl, sterically hindered hydroxylamine or sterically hindered hydrocarbyloxyamine moiety, L is independently of each other a direct bond or chemical linking group, FRM is independently of each other an organohalogen or an organophosphorus flame reatardant moiety, and x, y and z are each independently greater than or equal to 1, are especially effective towards providing flame retardancy to organic polymer substrates.
