Zusammenfassung:Disclosed is a flame retardant comprising bisphenol A bis(diphenyl phosphate) and its dimer, the former having an HPLC determined 78 to 87 area % and an 85 to less than 90 normalized area %, the normalized area % being based on the total HPLC area % of the bisphenol A bis(diphenyl phosphate) and the dimer. The flame retardant also has a low isopropenylphenyl diphenyl phosphate and a low triphenylphosphate content.
