Patent number: 5220015Abstract: 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. 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.Type: GrantFiled: April 3, 1992Date of Patent: June 15, 1993Assignee: Elf Atochem North America, Inc.Inventors: Ronald E. MacLeay, Terry N. Myers
