Using phosphorus oxychloride, nepentyl glycol and diaminodiphenylethel, a novel phosphorus-nitrogen containing flame retardant dineopentyl glycol P-diamino diphenyl ether diphoshonate was synthesized. The molecular structure of these title compounds were confirmed by elementalanalysis, IR, 1H NMR and MS. The TG and DSC analysis show the compounds have good antiflaming compatibility with polymers. Meanwhile, the compounds were applied to alkyd resin varnish and epoxy resin(E-44) to test their flame resistance. The results...
