摘要
A fluorine containing monomer was synthesized and its polymer was prepared by aromatic nucleophilic substitution polycondensation of the monomer and 4,4′ difluorobenzophenone using potassium carbonate as the catalyst and tetramethylene sulfone as solvent. The polymer properties were characterized by FTIR, NMR, DSC and the results showed that the T g of the polymer is 141 ℃ and the solubility of the polymer was obviously improved due to the introduction of (3 trifluoromethyl)phenyl group.
