When heated, PVC may lose hydrogen chloride and form a chromophoric conjugated polyene structure. 当受热时,PVC可能失去氯化氢并形成一种有色的共轭聚烯结构。
The Solutions of Reduced Order by Half to H ü ckel Determinant in Conjugated Polyene 共轭多烯Hückel行列式的折半降阶解法
The Infrared ( IR), Visible, and Ultraviolet ( UV-vis) spectra of products showed that the reaction speed of our method faster than Kise and Ogata's. Conversion was apparently elevated. Longer chain sequences of conjugated polyene structure were induced. 产物的FT-IR和UV-vis光谱表明,这一方法与Kise和Ogata的方法比较,反应速度大大加快,转化率明显提高,产生了链长更长的共轭链段。
