摘　　要：紫外光固化活性稀释剂双三羟甲基丙烷丙烯酸脂(Di-TMPTA)是由双三羟甲基丙烷与丙烯酸合成的,探讨了催化剂及用量、溶剂用量、反应时间和反应温度等因素的影响,确定了DiTMPTA的最佳合成条件,可得色泽好的产物,产品收率为90﹪。产品结构由红外光谱、1 H NMR和13C NMR确定。An UV-curable acrylic resin, ditrimethylolpropane acrylale （DTMPTA）, with low functionality was synthesized by esterification of ditrimethylolpropane and acrylic acid. The influences of the synthetic conditions such as catalyst, solvent, reaction time, and temperature were discussed in detail. The optimal synthesis conditions of Di-TMPTA were determined, and the resulting product had a yield of 90% and pale color. The chemical structure of Di-TMPTA was characterized by FT-IR, ^1H NMR and ^13C NMR spectroscopy.
