ABSTRACT:
Novel flame retardant compounds for polymers are disclosed that include 1,4-cyclohexanedimethanol bis(diphenyl phosphate)s. These can be synthesized by reacting 1,4-cyclohexanedimethanol and a diphenyl halophosphate, such as diphenyl chlorophosphate, in the presence of a catalyst, such as magnesium chloride, in an appropriate solvent, such as hexane.
