A novel poly(ether ether ketone) derived from 2-(6-oxide-6H-dibenz
〈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, 1H NMR and 31P NMR the product was a terpolymer, consisted of bisphenol A and difluorodiphenylketone. The DSC analysis show its Tg was 171℃. The copolymer was soluble in many polar solvents. -
