N2 - The preparation of (A-B)N block copolymers comprising of poly(aryl ether-sulfone) (PSF) and poly(tetrahydrofuran) (PTHF) segments have been described. Pyridine-terminated PSF oligomers of controlled molecular weights were synthesized via nucleophilic aromatic substitution reactions. PTHF oligomers prepared by living cationic ring-opening polymerization processes using trifluoromethanesulfonic anhydride as the initiator, were terminated with the PSF oligomers. The resulting block copolymers with quaternary nitrogen linkages along the backbone were characterized by a variety of techniques including spectroscopy, and thermal and chromatographic analysis.
