通过两步法制备改性酚醛树脂。首先，利用环氧酚醛树脂F-48与二甲胺反应，得到叔胺化酚醛树脂，叔胺化树脂被双氧水氧化后得到最终目标产物。该新型树脂易溶于水。然而，当加热到160℃时这种树脂就会变得不溶于水。通过DSC和TGA测试氧化叔胺树脂的热性能。实验制备了一种含有该树脂和红外染料的热敏膜，具有激光诱导成像功能。结果表明，这种氧化叔胺树脂可用于研发免化学处理热敏CTP版材。

A modified phenolic resin containing tertiary amine oxide was prepared via a two-step method. Epoxy phenolic resin, F-48, was reacted with dimethylamine to give the phenolic resin containing the tertiary amine group, which was then oxidized with hydrogen peroxide to obtain the target product. The tertiary amine oxide-containing resin could easily dissolve in water. However, it became water insoluble after heat treatment at a high temperature such as 160~C. Thermal properties of the tertiary amine oxide resin were studied with DSC and TGA. A thermo-sensitive film comprising the prepared resin and an IR-dye was prepared and laser-induced thermal imaging was also conducted. It is found that this material might be used to develop new chemistry-free CTP plates.
