摘　　要：以双环戊二烯等为原料合成一种新型三官能团液体脂环族环氧树脂.通过红外光谱、核磁共振氢谱及质谱等对其中间体及环氧树脂的结构进行了表征.所得脂环族环氧树脂采用阳离子引发剂二甲苯基碘六氟磷酸盐引发进行紫外光固化,对其光固化活性进行了研究,同时讨论了氧化剂过氧化苯甲酰对该光固化体系的增感作用.研究结果表明,新合成的脂环族环氧树脂采用二甲苯基碘六氟磷酸盐引发可以进行光固化,过氧化苯甲酰明显地加快了其光固化速度,固化膜具有较好的热稳定性.Started from dicyclopentadiene, a novel, liquid, trifunctional cycloaliphatic epoxide resin was synthesized and characterized. The photosensitivity of cationic photopolymerization of the resulting epoxide initiated by photoinitiator（ CH3-C6 H5 ）2I^＋ PF^-6 was studied. Meanwhile, the promotion of organic peroxide on photopolymerization of the epoxide was discussed. The results show that BPO could promote the initiation of （CH3-C6H5 ）2I^＋ PF^-6 significantly. The cured film of the synthesized epoxide has an excellent heat stability.
