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.
