通过环氧丙烯酸树脂和双羟基化合物反应，获得具有亲水性链段的水性环氧丙烯酸酯。
The epoxy acrylates oligomer with hydrophilic links and end waterborne modified-epoxy acrylates resin was prepared.
这种分散体系可作为一种紫外光固化水性涂料，其涂膜的耐磨性、柔韧性都比环氧丙烯酸酯涂膜增强，而硬度变化不大。
These dispersions can be used as waterborne ultraviolet-curable coatings, the abrasion and flexibility of their film are better than that of epoxy acrylate coatings, but the hardness decrease little.
