NEW COPOLYAMIDES CONTAINING AZOBENZENE GROUPS AND DIFFERENT DIACID AND DIAMINE IN THE MAIN CHAIN: SYNTHESIS AND CHARACTERIZATION

A new series of copolyamides CoPAs 7a-f were synthesized through the direct polycondensation reaction of 4,4'-azobenzenedicarboxylic acid 1 with 1,5-naphthalenediamine 2, 3,4-diaminobenzophenone 3 in the presence of adipic acid 4, fumaric acid 5 and terephthalic acid 6 as a second diacid in a m...
