丙烯酸双环戊二烯酯在UV固化反应中的FT-IR研究

Investigation on UV curing reaction of dicyclopentadienyl acrylate by FT-IR

用FT-IR对丙烯酸双环戊二烯酯(DCPA)中的丙烯酸双键和脂环双键在UV固化过程中和固化后的化学反应行为进行了研究。研究结果表明,在UV固化过程中丙烯酸双键几乎都反应掉,而脂环双键基本没有参与反应,而在UV固化后,脂环双键发生了加成反应。

Reaction behavior of the acrylic and the cyclic double bond of dicyclopentadienyl acrylate （DCPA） during and after UV curing were investigated by Fourier-Transform-infrared ray （FT-IR）. The results of research showed that during UV curing,the acrylic double bond cured almost finish,but the cyclic double bond didn＇t react in base. After UV curing,the cyclic double bond taked place addition reaction.
