Electroactive macromonomer a was synthesized by the oxidative coupling reaction of p-phenylene-diamine and b. This synthetic route protected the amine terminal group of N-phenyl-1,4-phenylenediamine from further reactions. Electroactive copolymers was synthesized by means of polycondensation from the macromonomer and 1,12-diaminododecane or 1,6-hexanediamine. The macromonomer was characterized with IR, MS and NMR. The electroactivity of the macromonomer and copolymers were studied by UV and CV.
