Abstract : Our research is focused on the general synthesis and characterization of new classes of thermoplastic and thermosetting engineering polymers from thiophene-based monomers and recently discovered synthetic methodologies. The approaches involve detailed investigations of the synthesis of thiophene-based poly(aramide)s, aromatic and aliphatic poly(ester)s, poly(benzbisoxazole)s, poly(arylene ether ketone)s, poly(imide)s, poly(arylene)s and poly(arylene sulfide)s using inexpensive monomers synthesized from thiophene-2,5-diacid chloride (made in > 90% yield from adipic acid and thionyl chloride!) and halothiophene derivatives. jg p8
