A novel compound,P-carboxphenylphosphinic acid(CPPPA),was synthesized by oxidation of the intermediate prepared from the Friedel-Crafts reaction of dichlorophenylphosphine and toluene catalyzed by anhydrous aluminium chloride.The yields of the target product were from 10.3% to 30.8%.It was found that the initial decomposition temperature of CPPPA iS comparable with CEPPA.The decomposition temperatures at 5%,10%and 50%mass IOSS of CPPPA were much higher than those of CEPPA,and the char forming ratio of CPPPA was also higher than that of CEPPA.Thus CPPPA is a potential flame retardant with good property for PET.
