  The invention relates to a method of producing imide bond-containing resins and flame retardants comprising such resins. The method comprises subject­ing a halogenated phthalic anhydride, a specific copolymer and a diamine to dehydration reaction in an inert solvent to give an imide bond-containing resin. The resins provide flammable substances with good fire or flame resistance and at the same time themselves have good heat resistance and weather resistance. Therefore, the flame retardants comprising these resins have a wide field of application.

  This invention provides novel hindered amine light stabilizers with flame retardant properties having, e.g., the following Formula I wherein R is, e.g., chlorine or bromine substituted phthalimide, R1, R2 and R3 are, e.g., hydrogen, and Y is, e.g., a direct bond. 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.
