在1.5 GPa以上的压力下，氰基乙炔在固相中进行了聚合反应。反应产物的拉曼光谱研究表明，该聚合物具有共轭的线性主链，并具有CN悬垂基团。该取代聚乙炔的拉曼光谱显示出与反式聚乙炔相似的共振行为。共轭体系中与π -π *跃迁相关的光学间隙小于反式聚乙炔，这可能是由于CN三键和共轭双键之间的共振相互作用。
Cyanoacetylene underwent polymerization reaction in a solid phase at pressures above 1.5 GPa. The Raman study of the reaction product showed that the polymer had a conjugated linear backbone with CN pendant groups. The Raman spectra for this substituted polyacetylene demonstrated a resonance behavior similar to that reported for trans‐polyacetylene. The optical gap associated with the π–π* transition in the conjugated system was smaller than that of trans‐polyacetylene, probably due to the resonance interactions between the CN triple bonds and the conjugated double bonds.
