Abstract :
Poly(4,4′-diphenylamine-3,5-di-tert-butoxybenzylidene) was synthesized with a dehydrative polycondensation by using H2SO4 as a catalyst. The polymer was oxidized with PbO2 to generate a stable radical group in the polymer. The color of the polymer changed from green to dark red upon the oxidation. ESR spectrum showed not only a signal with g value of 2.004, but also so-called “halffield” signals with g value of 4.288.
