WebNov 15, 2024 · This study focuses on the experimental and molecular-level investigation of epoxy acrylate formation. Epoxy acrylate vinyl ester resin was prepared by a reaction of diglycidyl ether of bisphenol-A-based epoxy resin and acrylic acid, using benzimidazole as a catalyst. It was confirmed that benzimidazole can effectively catalyze this reaction. FTIR … Weba catalyst was observed at 233°C. In the BMI system catalyzed by TPP, an exothermic peak was observed at 168°C. TPP catalyst clearly lowered the curing tempera ture of BMI.
