【Abstract】 A new monomer,1,4 (2 methyl 4 hydroxy phenyl) 2,3 phthalazion 1 one, was successfully prepared and used to synthesize a novel high performance engineering plastics with 4,4′ diflourodiphenylketone in the presence of anhydrous carbonate(M 2CO 3) in an aprotic solvent. The IR spectra of the new monomer and the novel polymer indicate the reaction has taken place as expected. The inherent viscosity of the polymer is over 0.44×10 2 mL/g and the DSC shows its glass transition temperature is 247.95 ℃. The polymer is soluble in solvents such as chloroform, tetrachloroethane, NMP, etc.and it can easily be cast into flexible, yellow and transparent film.更多还原
