Abstract: | A novel block copolymer of polyglycolide (PGA) and aniline pentamer that is electro-active and degradable was synthesized. The copolymer was prepared by low-temperature polycondensation between carboxyl-capped aniline pentamer and hydroxyl-capped PGA, with N,N′-dicyclohexylcarbodiimide (DCC) as dehydrating agent. The structures of monomers and the copolymer were characterized by IR, 1H NMR. The chemical redox process of the as-prepared copolymer was studied by UV-vis spectra and cyclic voltammetry (CV). Thermal analysis and the study of degradation show that the copolymer has good thermal stability and degradability. |
