摘要

以高含氢硅油（甲基氢硅油）为原料，通过与苯乙烯、4-乙烯基环氧环己烷在Lamoreaux催化剂作用下的硅氢加成反应，制备了具有苯环侧链的脂环族环氧有机硅预聚体（Ep-Ph-SiO）。利用1H-NMR确定了芳环、环氧和硅氢嵌段的比例关系，得到了Ep-Ph-SiO的平均组成；同时测定了Ep-Ph-SiO的折射率。以4-（苯硫基）苯基二苯基硫鎓六氟磷酸盐为光引发剂，考察了Ep-Ph-SiO在高压汞灯辐射下的阳离子光固化。研究发现，所制备的含苯基脂环族环氧有机硅预聚体能有效地发生阳离子光固化，光固化活性高于常用的缩水甘油型环氧预聚体；随着苯环含量的增加，树脂折射率提高。

Abstract

Phenyl cycloaliphatic epoxy-silicone oligomers (Ep-Ph-SiO) with different contents of benzene rings and epoxy groups were synthesized via sequential hydrosilylation reactions of methylhydrogen silicone oil by attaching styrene first, which was followed by reacting with 4-vinyl-1-cyclohexene-1,2-epoxide in the presence of Lamoreaux catalyst. The contents of benzene rings and epoxy groups in the monomers were determined by 1H-NMR. The refractive indices (RIs) of the obtained oligomers were measured and the cationic photo-polymerization of these oligomers was studied by using triarylsulfonium hexafluorophosphate (P-S) as photo-initiators exposed to a high-pressure mercury lamp. The results showed that the phenyl cycloaliphatic epoxy-silicone oligomers exhibited higher photo-polymerization activity than diglycidyl ether of bisphenol-A epoxy resins and the benzene rings could improve the RIs of cycloaliphatic epoxy-silicones.Cited
