以多羟甲基苯酚钠和丙烯酰氯为原料，合成了适用于水性UV固化涂料的多羟甲基苯酚丙烯酸酯，通过红外光谱表征了产物的化学结构。探讨了物料比、反应温度、反应时间和催化剂用量等因素对产物产率的影响，结果表明：当n(多羟甲基苯酚钠)∶n(丙烯酰氯)=1∶2、反应温度为0~-5 ℃、反应时间为2.5 h、催化剂四丁基溴化铵用量为0.04%（占物料质量比）时，最有利于产物的合成；多羟甲基苯酚丙烯酸酯的水溶性及涂膜性能，也能较好地满足水性UV固化涂料的应用。

Multi-hydroxymethyl-phenol acrylate which is suitable for waterborne UV curing coating was synthesized by using multi-hydroxymethyl phenol sodium and acryloyl chloride as raw material. Chemical structure of the product was characterized by FT-IR. The relation between the production yield and material ratio, reaction temperature, reaction time and catalyst content was discussed. The results showed that the most favorable reaction condition is when n(multihydroxymethyl phenol sodium)∶n(acryloyl chloride)=1∶2, reaction temperature at 0~- 5℃, reaction time 2.5 h, the content of tetrabutyl ammonium bromide 0.04%(accounting for materials quality ratio); water-soluble and film properties of the multi-hydroxymethyl-phenol acrylate can satisfy the application of waterborne UV curing coating.
