摘 要: 用自动记录膨胀计法研究了光引发剂安息香二甲醚(BDK)、安息香乙醚(BE)、安息香异丙醚(BIP)、2-羟基,2-甲基苯丙酮(Darocur 1173)和二苯甲酰单环缩乙二醇酮(DBEK)对不饱和聚酯-丙烯酸酯体系的引发活性和贮存稳定性,结果表明:引发活性是BDK>Darocur 1173>BE>BIP>DBEK,贮存稳定性是BDK>Darocur 1173>BIP>BE。 The photoinitiation activity and shelf life of 5 photoinitiators in unsa- turated polyester-acrylate system were studied by using dilatometry. It was shown that the photoinitiation activity of the photoinitiators decreases in the order of benzyl dimethoxyketal (BDK)>dimethyl-hydroxy-acetophenone (Daro- cur 1173)>benzoin ethyl ether (BE)>benzoin isopropyl ether (BIP)>benzil ethyl- ene ketal, while the shelf life declines in the order of BDK>Darocur 1173 >BIP>BE.
