Several novel polyarylether sulfones containing different alkyl substituents were synthesized by "one-step" solution polycondensation reaction of 2',2"-dimethylphenolphthalein,2',5',2",5"-tetramethylphenolphthalein,and 2',2"-diisopropyl-5',5"-dimethylphenolphthalein with bis(4-fluorophenyl) sulfone in the presence of anhydrous K₂CO₃.Their structure and properties were characterized by FTIR,differential scanning calorimetry,thermogravimetry,etc.While maintaining high glass transition temperature,excellent heat-resistant and mechanical properties of phenolphthalein based polyarylethersulfone,the solubility of the polymers prepared were improved greatly.The results indicate that the polymers may have potential applications for gas separation membrane.
