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