摘要

Poly(aniline-co-o-aminobenzenesulfonic acid) (PAOABSA) as a water soluble conducting polymer was synthesized by chemical polymerization. The productivity and the room-temperature conductivity of the copolymer were measured as a function of the reaction conditions, such as reaction temperature, the ratio of oxidant to monomer and the degree of sulfonation defined as the ratio of sulfur to nitrogen atoms(S/N). The main results obtained are summarized as follows: (1) lower reaction temperature (at about 0℃) is favorable for the enhancement of the room-temperature conductivity of the copolymer; (2) higher content of oxidant is unfavorable for increasing the room-temperature conductivity of the copolymer; (3) both productivity and room-temperature conductivity of the copolymer decrease with increase of the degree of sulfonation which was always lower than 0.5 even an excess of o-aminobenzenesulfonic acid was added, probably because the reactivity ratio of aniline (γ1=2.99 ± 0.05) is much higher than that of o-aminobenzenesulfonic acid (γ2 = 0.06± 0.02) estimated by using Fineman-Ross method and least square method.
