Study on Impurities in Polyacetylene by Neutron Activation Analysis

抄録

The species and concentration of impurities in polyacetylene films have been analyzed by neutron activation technique. It is found that the films prepared by the standard procedure are contaminated with catalyst residue up to the level of ca. 10³ ppm. Extensive washing with HCl-ethanol solution is effective for dissolving out the catalyst residue but causes the enhancement of the electrical conductivity of the films.
