Abstract
Polyacetylene doped with potassium or rubidium cations (and optionally with other alkali metal cations) is heat treated at 60.degree.-400.degree. C., preferably 100.degree.-250 .degree. C., to achieve greatly enhanced room temperature conductivity. Products with relative conductivities 150%, 300%, 450% or more of the conductivity prior to heat treating are obtained, with room-temperature conductivities of 300 S/cm, 450 S/cm, or higher.
