| Abstract: | The electrical conductivity of polyacetylene, prepared as a free-standing film, changes drastically when treated with aqueous solutions of nitrate in the presence of sulphuric acid (5.7 M). Linear calibration plots are obtained for 2–40 × 10?3 M nitrate. Common non-oxidating ions do not interfere. |
