A novel poly(ether ether ketone) derived from 2 (6 oxide 6H dibenz〈c, e〉〈1, 2〉oxa phospho rin 6 yl) 1,4 dihydroxyphenylene, 4, 4′ diflourodiphenylketone and bisphenol A was synthesized by solution polycondensation. The influences of reaction time, and concentration of reactants on the polymerization were investigated . A copolymer with inherent viscosity of 1 44 was obtained. As characterized by FT IR, 1 H NMR and 31 P NMR the product was a terpolymer, consisted of bisphenol A and difluorodiphenylketone. The DSC analysis show its T g was 171 ℃. The copolymer was soluble in many polar solvents.
A novel phosphorus-containing copolycarbonate was synthesized from bisphenol-A,2-（6-oxido-6H-dibenz<1,2>oxa phosphorin-6-yl）-1,4-dihydroxy phenylene（ODOP-HQ） and triphosgene by interfacial polycondensation,and a copolycarbonate with an inherent viscosity of 0.53 dL/g was obtained.The（copolymer） was characterized by elemental analysis,FT-IR,DSC,TGA,and NMR.DSC result shows that the Tg of the copolycarbonate is 149 ℃,which is higher than that of normal PC.The TGA（result） shows that the onset decomposition temperature of the copolycarbonate is 355 ℃,which indicates it（possesses） a good thermal stability.
