一般描述

双环戊二烯（DCPD）是环戊二烯的二聚体，由两个不饱和双键组成（一个在降冰片烯环上，一个在环戊烯环上）。DCPT 可单独用于聚合物中，也可与其他碳氢化合物一起使用。它也用于制药、弹性体、聚碳酸酯和聚酯树脂。

应用

双环戊二烯可用于：
  • 采用 VARTM（真空辅助树脂转移模塑）工艺制备 CF/p-DCPD（碳纤维/聚双环戊二烯）复合材料。
  • 在 η5-环戊二烯基三（二甲基氨基）锆催化剂的制备中。
  • 在纤维素–马来酸酐–双环戊二烯共聚物基体的自由基聚合合成中。

特点和优势

DCPD 与邻苯二甲酸和间苯二甲酸聚酯相比具有以下优点：
  • 低收缩率
  • 降低成本效益
  • 减少苯乙烯的排放
  • 薄层快速固化

Zinc(II) oxide nanoparticles were used for the stabilization of dicyclopentadiene (DCPD)-water-based high internal phase emulsions (HIPEs), which were subsequently cured using ring-opening metathesis polymerization (ROMP). The morphology of the resulting ZnO-pDCPD nanocomposite foams was investigated in correlation to the nanoparticle

Cyclic Ru-phenolates were synthesized, and these compounds were used as olefin metathesis catalysts. Investigation of their catalytic activity pointed out that, after activation with chemical agents, these catalysts promote ring-closing metathesis (RCM), enyne and cross-metathesis (CM) reactions, including butenolysis, with
