New Polymer Syntheses Part 60: A Facile Synthetic Route to Polyamides Based on Thieno[2,3-b]thiophene and Their Corrosion Inhibition Behavior
Polyamides containing thieno[2,3-_b_]thiophene moiety were prepared _via_ a simple polycondensation reaction of the diaminothieno[2,3-_b_]thiophene monomer 1A with different kinds of diacid chlorides (including oxalyl, adipoyl, sebacoyl, isophthaloyl, terephthaloyl, 4,4′-azodibenzoyl, 3,3′-azodibenzoyl, _p_-phenylene diacryloyl) in the presence of LiCl and NMP as a solvent through low-temperature solution polycondensation. The chemical structures of model compound and synthesized polyamides were confirmed by FTIR, nuclear ... Read more
