## Abstract Two reactive polysulfones with carboxylic side groups were synthesized by polycondensation of different amounts of 4,4โ€bis(4โ€hydroxyphenyl)pentanoic acid (1) and 2,2โ€ฒโ€isopropylidenediphenol (bisphenolโ€A,2) with bis(4โ€chlorophenyl) sulfone (3). The amorphous polycondensate 4a was cast fr
