ABSTRACT Resins are prepared from polysulfone and polyethersulfone polymers that bear functional groups derived from compounds that are condensation products of amino-phenols and acid anhydrides. The polymers are prepared by correacting aromatic compounds holding two hydroxyl groups, aromatic compounds holding two active halogen groups, and the condensation product of amino- phenol and acid anhydride, the condensation product holding one hydroxyl group. The resulting product has a molecular weight between about 1,000 and 40,000, preferably between about 5,000 and 30,000, and can be cross-linked to form a resin that is thermoplastic and solvent resistant.
