Novel flame retarding compounds that comprise at least one sterically hinder ed nitroxyl, hydroxylamine or hydrocarbyloxyamine moiety and at least one conventional organohalogen or organophosphorus flame retardant moiety, represented by (I) 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 o r 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. |
