A series of polyarylethersulfone copolymers containing phenolphthalein segments were successfully synthesized (APS
SPS
HPS and CPS). A preliminary study on the copolycondesa-tion process showed that the presence of phenolphthalein component can accelerate the reaction
Copolymers were characterized by Reduced Viscosity
1H
13C-NMR and IR. The Tg of copolymers smoothly increases with the increase of the amount of phenolphthalein component. All the copolymers were proved to be random and amorphous by IR
