A Reactive Cyclic Phosphonamide Flame Retardant for Epoxy Resins

摘要：

　　To take the advantage of the reactivity of five-membered cyclic phosphorus compounds, 1,2,3-tri-phenyl-1,3,2-diazaphospholidine-2-oxide (TPDPO) was explored as a reactive flame retardant for epoxy resins (EP).Through the model compounds, it is established that TPDPO reacts with the secondary hydroxyl group, but is inert toward aryl amino and epoxide groups.At a loading of only 8 wt% (0.74 wt% phosphorus), TPDPO enables the cured epoxy to achieve a UL-94 V0 rating.TGA-FTIR analysis of the gaseous products proves that the excellent flame retardancy of TPDPO-EP is partly due to the enhanced dehydration process of the epoxy.
