A novel photosensitive epoxy-phenolic resin which can be soluble in 0.2% Na_2CO_3 solution has been synthesized by using the photosensitive epoxy-phenolic resin chain-extended by diaminoethane. The synthetic technique and parameters have been examined.
以乙二胺扩链光敏酚醛环氧树脂为原料合成了一种可以在质量分数为02%的Na2CO3水溶液中具有最佳溶解性能的光敏酚醛环氧树脂。
It was found that diaminoethane and hexadecylamine acting as the buffering reagents for controlling the pH value and concentration of free Cu2+ in the solution play a critical role to avoid Cu2+ being reduced to Cu.
乙二胺和十六烷基胺在反应体系中充当缓冲试剂，调节反应液的pH值并控制体系中游离Cu2+的浓度，使得Cu2+不会被迅速还原成单质铜。
