摘要: 本文用羟基对甲苯磺酰氧基碘苯与聚苯乙烯进行亲电取代反应,得到大分子阳离子碘鎓盐光引发剂聚苯乙烯碘鎓-六氟锑酸盐(PS-I·SbF6).用核磁共振仪、傅立叶红外光谱仪、凝胶渗透色谱仪、差示扫描量热仪、紫外分光光度仪对其进行了表征.与小分子碘鎓盐系光引发剂相比,PS-I·SbF6的紫外最大吸收波长λmax红移,在240-270 nm范围内有较强的吸收;固化成膜后其相对迁移率较小分子光引发剂有显著下降.初步研究了PS-I·SbF6在环氧体系中的光固化性能,结果表明该体系有较好的光固化和后固化特性.

Abstract: In this article,a novel Cationic Macropbotoinitiator Polystyrene-iodonium hexafluoroanti-monate (PS-I·SbF6) was prepared by the reaction of Polystyrene with [hydroxy(tosyloxy)iodo] benzene.The later product PS-I·SbF6 was identified by 1H-NMR,FTIR,GPC,DSC,and UV spectrum.The red shift phenomenon was observed in the ultraviolet spectrum of PS-I·SbF6,itsλmax moved from 227 to 260 nm,so it can well match with mercury lamp.Compared with the small molecular iodonium photoinitiators,its relative migration ratio in the cured film was much lower. The photoinitiation activities of the epoxy system in which PS-I·ShF6 as a cationic photoinitiator were studied.Results showed that the system had good curing and post-curing ability.

Key words: iodonium salt, cationic macrophotoinitiator, UV curing, photoinitiation activity
