The Study of Ethoxyated Bisphenol a Dimethacrylates

摘要

In this paper, Ethoxyated bisphenol A dimethacrylate was synthesized form Ethoxylated Bisphenol A and acrylic acid by direct esterification route. The effect of factors such as mixture ratio of raw materials, content of catalyst, content of polymerization inhibitor, reaction time on yield was researched carefully and obtained the optimum process conditions of ethoxyated bisphenol A dimethacrylate. The final product data: acid number＜0.15 mg KOH/g, solid content＞99%(105°C, 20min), yield＞86%, the colour number could reduce less than NO 80 using FA30 during esterification. Product data could reach internal lever in the same kind of product.
