抄録

Electron Spin Resonance studies of diarylbutadiynes such as diphenylbutadiyne and p,p′-butadiynylenedi(methyl benzoate) have shown that these compounds contain free radicals at room temperature and that the number of radicals in the solid state increases with temperature. The color of diphenylpicrylhydrazyl (DPPH) disappears when these diacetylenes are added, indicating that the stable DPPH radicals react with the diacetylenes. The results suggest a probable initiation mechanism of the polymerization of the diacetylenes which do not undergo topochemical polymerization.
