摘要

用丙烯酰氯对新型水溶性丙烯酸酯季铵盐酚醛树脂的羟基进行了反应，羟基是由丙烯酸及叔胺盐与环氧酚醛树脂开环反应生成的.讨论了反应时间、反应温度、丙烯酰氯用量对羟基转化率的影响，并比较了丙烯酰化前后树脂在光交联时凝胶含量的变化.结果表明，最佳反应条件为：丙烯酰氯/羟基摩尔比为1.5

温度40～50 ℃

时间1～2 h.羟基转化率可达75%以上.产物在紫外光交联时凝胶含量比未反应前高1倍.

Abstract

This paper deals with acrylation of hydroxyl groups of a new type water soluble acrylate and quaternary ammonium salt groups-containing phenolic resin using acryloyl chloride. The hydroxyl groups were formed during ring-opening reaction of epoxy phenolic resin with acrylic acid and triethylamine hydrochloride. Effects of reaction time

reaction temperature

molar ratio of acryloyl chloride/OH on conversion of hydroxyl group are studied. Photosensitivity of the acrylated resin with that of unacrylated one is compared. The results show that the optimum reaction conditions are: the molar ratio of acryloyl chloride/OH of the resin=1.5/1

the reaction temperature is 40～50 ℃ and the reaction time is 1～2 h. The hydroxyl groups of the acrylate and quaternary ammonium salt-containing phenolic resin after reaction with acryloyl chloride are converted more than 75% to acrylate groups and the photocrosslinked gel of the resin after modification is almost twice of that before modification.
