    Abstract: Polymeric flame retardants comprise halogenated aromatic compounds having acylamino functional groups which are chemically bonded to cyclic imide-containing or imide-forming polymers or copolymers, which polymeric flame retardants have, e.g., the following Formula 1 or II:
    in which the units occur, e.g., in the polymer backbone; R1 and R2 are, e.g., hydrogen; and G is a flame retardant group attached to the unit by an acylamino functional group having linked thereto a halogenated aromatic ring. The polymeric flame retardants are prepared by the reaction of halogenated aromatics containing a reactive hydrazido group with some or all of the anhydride groups of an cyclic alpha,beta-unsaturated dicarboxylic acid anhydride polymer or copolymer to form pendant halogenated-aromatic-substituted imide or amic acid groups. In addition, polymeric flame retardants are used to render thermoplastic resins less flammable under conditions which promote combustion. Novel flame retardant hydrazides are disclosed.

    Abstract: Stabilized polyurethanes, polyureas and polyurethane-polyurea polymers having hindered amine light stabilizers (HALS) bonded thereto by means of a hydrazide functionality attached to the HALS are provided. The synergistic effect of a second amide functional group in the HALS-hydrazide provides improved photostabilization efficiency as compared to HALS-hydrazides of the prior art.
