Halogen-free Flame Retarding Materials Based on Bisphenol Triazole Resins and Polymers

This technology provides a new class of superior halogen-free flame retarding polymers and epoxy and cyanate ester resins, as well as methods of synthesizing such novel flame retarding materials. These flame retardants exhibit exceptional heat release properties, such as ultra-low heat release capacities and high char yields. Unlike other halogen-free low-flammability polymers, the novel polymers can be processed thermally (without additives) to further broaden potential commercial applicability. The novel epoxy and cyanate ester resins can function as curing agents/catalysts as well as thermosetting resins, resulting in simple material preparation and effective adhesion in a non-flammable and non-halogenated formulation.
