A process for the preparation of a stabilized electrically conductive polymer having a conductivity greater than 10-2 S/cm, comprising treating an organic unsaturated polymer of the series of the polyphenylenes, heteropolyphenylenes or polyacetylenes, in the absence of moisture and of oxygen, first
A process for the preparation of a stabilized electrically conductive polymer having a conductivity greater than 10-2 S/cm, comprising treating an organic unsaturated polymer of the series of the polyphenylenes, heteropolyphenylenes or polyacetylenes, in the absence of moisture and of oxygen, first with from 0.1 to 10.5% by weight, based on the polymer, of an organic nitroso compound selected from the group consisting of ethyl N-nitroso-N-methylcarbamate, N-nitroso-N-methyl-urethane, 1-nitrosonaphth-2-ol, 2-nitrosonaphth-1-ol, the ammonium salt of 4-nitroso-N-phenylhydroxylamine (Cupferron), 2-nitroso-toluene, 5-nitroso-2,4,6-triaminopyridine, 3-nitrosostyrene, w4-nitroso-N-dimethylaniline, N-(N-nitrosomethylamino)-methyl-benzamide, 2-nitroso-2-naphthol-3,6-disulfonic acid, N-nitrosopyrrolidone and 4-nitrosophenol, at from -100°C. to +100°C. for from 0.1 to about 5 hours, and then with from 0.5 to 55% by weight, based on the polymer, of a strong Lewis acid dopant having a pka of from -10 to +4 or a base having a Pauling electronegativity of up to 1.5.
