LIGHT STABILIZING FLAME RETARDANTS Abstract of the Disclosure This invention provides novel hindered amine light stabilizers with flame retardant properties. The compounds of this invention protect polymeric compositions against the degradative effects of heat and light and simultaneously improve the flammability rating of the polymeric composition, while also contributing antioxidant and metal deactivation properties to the polymeric compositions. The compositions of this invention are prepared by reacting halogenated flame retardant containing a cyclic anhydride group with hindered amine light stabilizers containing primary amino or reactive hydrazido functional groups. The preparation of the novel compositions may be carried out in inert solvents or in inert polymeric compositions in a melt blending step.
