Abstract: 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.

Key words: polyarylethersulfone, synthesis, characterization
