摘要
合成了环氧有机硅光敏预聚物及阳离子光引发剂甲苯茂铁四氟硼酸盐 ,研究光引发剂种类、预聚物与单体配比、增感剂结构等因素对固化速度的影响 ,发现预聚物体系的感度较高 ,最小感度值为 1 65mJ/cm2 ;
A photosensitive oligomer,cycloaliphatic epoxy polysiloxane,and a new kind of cationic photoinitiator,[CpFe(η 6 tol)]BF 4,was synthesized.The influences of photoinitiators,ratio of oligomer to monomer,and promoters on the rate of photoinitiated cationic polymerization of cycloaliphatic epoxy polysiloxane systems were studied.It shows that the polysiloxane is a high photosensitive oligomer,with a 165 mL/cm 2 optimized photosensitivity when initiated by diaryliodonium salt SR 1012 with sensitizer 651. Moreover,the ability of dark cure of the polysiloxane when initiated by [CpFe(η 6 tol)] BF 4was discussed.
