| 摘 要： | 合成了两种大分子光引发剂PPI 1和PPI 2，紫外吸收行为均与4-BP相似，摩尔消光系数比4-BP高，且光解速率快。在不加助引发剂EDAB条件下引发单体HDDA聚合效率良好，对比PPI 1和PPI 2，随着吸光基团官能度（分子量）增大，聚合速率增加、最终转化率增高。将各自诱导单体PEGDA聚合的固化膜，在二氯甲烷溶液中浸泡5天后，PPI 1的萃取量是4-BP的44.5%，PPI 2的萃取量是4-BP的40%，说明PPI 1和PPI 2都是引发效率良好的低迁移光引发剂。

| Abstract: | Two macromolecular photoinitiators PPI 1 and PPI 2 were synthesized and characterized. The results showed that the UV absorption behavior of PPI 1 and PPI 2 are similar to that of 4-BP, the molar extinction coefficient are higher,the rate of photodegradation are faster. Without the addition of EDAB,compared to PPI 1 and PPI 2, as the molecular weight (functionality) of photoinitiator increased, the polymerization rate increased and the final double bond conversion rate of HDDA increased. The extraction amount of film cured by PPI 1 was 44.5% than that of 4-BP,PPI 2 was 40% than that of 4-BP respectively,after immersed in CH2Cl2 solution for 5 days. |
