摘要：
A process for the preparation of an electrically conductive polyene, wherein a polyene which contains one or more chain members of the formula where R is hydrogen or methyl, and which contains a total of not less than seven aliphatic double bonds, is treated, in the absence of moisture and of oxygen, with a strong Lewis acid having a pk.sub.a of from -10 to +4, or with an alkali metal.
