Eight alkyl phosphoric dialkyl esters were synthesized by reacting potassium dialkyl phosphite with different halohydrocarbons in the presence of quaternary ammonium salt and KOH. Their structures were identified by IR and NMR. The mixtures of epoxy resin with phosphonates showed a better flame retardancy and plasticization than that with phosphates.
