Epoxy resins represent a very important class of polymers. They find use in a wide variety of applications, notably as adhesives in the construction of electronics and other consumer goods. As with other organic polymers, epoxy resins are intrinsically flammable and must be flame retarded to ensure safety through the lifespan of the product. Traditionally this was accomplished using organohalogen compounds such as tetrabromobisphenol A and polybrominated diphenyl ethers. In recent years, health concerns associated with halogenated flame retardants have become apparent, creating an urgent need for replacement. Organophosphorus compounds have emerged as potential alternatives. Incorporating organophosphorus functionality into the backbone of an epoxy is an attractive option to prevent migration over time. To accomplish this, the diol 1-dopyl-1,2-(4-hydroxyphenyl)ethene was synthesized from desoxyanisoin and used as a curing agent for the diglycidyl ether of bisphenol A (DGEBA) epoxy resin.
