摘　　要：合成了一种可紫外光聚合的助引发剂——叔胺型聚氨酯丙烯酸酯,对中间体及产物进行了表征。研究了将叔胺型聚氨酯丙烯酸酯和二苯甲酮配合用于紫外光固化体系的光引发,结果表明叔胺型聚氨酯丙烯酸酯参与了光固化过程,与单独采用二苯甲酮光引发剂相比,它可提高体系的C=C双键速率和转化率,且随着添加量的增大,C=C双键转化速率加快,在相同的光照条件下,C=C双键转化率升高。A new type of photo curable co-initiator, polyurethane acrylates with tertiary amine moiety（APUA）, is prepared, and the Michael-addition intermediate and APUA are analyzed, and their structure is characterized. The PUAA/ benzophenone combined initiator is used in photo-curable systems and the photo-polymerization rates are determined by FT-IR. The results indicate that APUA can take part in photo-polymerization and increase the photo-polymerization rate and C =C double bond conversion rate. The more APUA is used, the faster the photo-polymerization rate and the higher conversion of C =C double bond can be.
