Abstract:A series of modified aromatic oxadiazole polymers were synthesized via condensation reactions of terephthalic dihydrazide (TPH) and varying amounts of Trimesic acid (H3BTC) in polyphosphoric acid (PPA). Pentaerythritol was introduced to construct intermolecular hydrogen bonds among polymeric chains, resulting in a three-dimensional network structure, and correlations between H-bonds and mechanic properties are discussed. Structures and mechanic properties of the polymers were characterized and analyzed. By inv… Show more
