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.
这项发明提供了具有阻燃性能的新型受阻胺光稳定剂。该发明的化合物可保护聚合物组合物免受热和光的降解作用,并同时改善聚合物组合物的易燃等级,同时还为聚合物组合物提供抗氧化和金属失活特性。该发明的组合物是通过将含有环状酸酐基团的卤代阻燃剂与含有主要氨基或反应性肼基官能团的受阻胺光稳定剂反应而制备的。制备新型组合物可以在惰性溶剂或惰性聚合物组合物中进行熔融混合步骤。
