Electroactive poly(amic acid), with oligoaniline in the main chain, was synthesized from macro-monomer of oligoaniline and p-phenylenediamine by oxidative coupling polymerization. The polymer characterization included Fourier-transform infrared spectra (FTIR), 1 H nuclear magnetic resonance spectra ( 1 H NMR) and gel permeation chromatography (GPC) as a determination of polymer structure,...
A series of blends of thermoplastic polyurethane(PU) and polyether–polyimide (PI) were prepared in two steps. The first step was the preparation of polyether–amic acid by the reaction of an oligmer based on polytetramethylene oxide glycol di-p-aminobenzoate (APTMO) of different molecular weight (650, 1000, and 2000) with benzenetetracarboxylic acid dianhydride (PMDA). The second step was mixing polyether–polyurethane...
