Abstract
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 tetr amethylene 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 d egrees C and the solubility of the polymer was obviously improved due to th e introduction of (3-trifluoromethyl) phenyl group.
