| 摘 要： | 鎓盐引发的阳离子光聚合已有很多报道,但多偏重于低分子量环氧化合物的溶液聚合,对环氧树脂薄膜本体聚合的报道较少。鎓盐在紫外区(>300nm)吸收光的能力很低,苯偶姻醚可促进氟硼酸二苯碘Ph_2I BF_4~-]在300—400nm的光分解,从而有助于它引

| Abstract: | Diphenyliodonium fluoroborate(Ph_2I~ BF_4~-)is found to be an effective photoinitiator forthe cationic polymerization of epoxypolysilicone, and benzoin alkyl ethers can promote thisphotoinitiated polymerization. The order of promotion was: benzoin dimethyl ether>benzoinisopropyl ether>benzoin methyl ether. |
