阴离子对邻甲基苯胺化学聚合的影响

THE EFFECT OF ANIONS ON THE CHEMICAL POLYMERIZATION OF o-METHYLANILINE

苯胺在酸性溶液中经化学和电化学氧化所得聚合物有良好的导电性和很高的稳定性。由于导电高聚物的不溶和不熔,使许多研究工作难以深入,实际应用也受到限制,在导电高聚物方面存在的这些实际问题促使了对可溶性导电高聚物合成的研究。通过化学法合成可溶性聚(o-,m-)甲苯胺的研究结果表明,甲基在苯环上的位置对聚苯胺衍生物的电导率、溶解性等都有较明显的影响。最近,通过电化学聚合合成了聚邻甲基苯胺。

The conductivities and yields of poly-o-methylaniline obtained from the aqueous mediaof HBF_4, HCl, H_2SO_4, and H_3PO_4 are reported. The HBF_4 was found to be more favourablefor the polymerization of o-methylaniline(o-toluidine), the conductivity of product therebywas 0.47 to 1. 0 S·cm^(-1) at mole ratio of (NH_4)_2S_2O_8/C_7H_9N = 1:2 to 1:3. position 591.9nmin the UV visible spectra of poly-o-metbylaniline obtained in HBF_4 medium, The peak wasaffected by the anion of the medium, but 310.3 nm was independent of the anior.
