Item Development and testing of flame retardant additives and polymers(2004) Jurs, Joshua Lewis; Tour, James M.The first chapter examines the non-halogenated flame retardant additives. The synthesis and blending of these various boron compounds are discussed and the blending of these additives into commercial polymers is addressed. The burn results of these polymer and additives blends are displayed. Chapter 2 shows the various halogenated flame retardant additives, based on the insecticide DDT and its many analogs. The synthesis and blending of these various halogenated flame retardant additives in several commercial polymers is examined. The burn results for these additives are shown and all perform as V-0 material in the UL-94 flammability test, when they are mixed with a synergist (antimony oxide) and an anti-drip additive (polytetrafluoroethylene). These compounds represent a new class of halogenated flame retardant additives, which could be used in commercial polymers. The third chapter outlines the new approach in making flame retardant polymers out of the DDT monomer and its various analogs. The synthesis and blending of these new flame retardant polymers into commercial plastics is examined. The burn results of these new polymer blends are summarized. Chapter 4 examines a new class of inherently flame retardant polymers, which incorporates the bisphenol C structure into these new polymers. The synthesis and blending of these novel flame retardant polymers is outlined. The burn results for these new polymers show that they all work as inherently flame retardant polymer without the need for a synergist. These polymers represent a new class of inherently flame retardant polymers.
