  一种可聚合光引发剂的制备方法

  摘要：

  本发明一种可聚合光引发剂的制备方法，以甲基丙烯酸和2‑羟基‑4'‑(2‑羟乙氧基)‑2‑甲基苯丙酮为原料，采取直接酯化法制得可聚合的光引发剂。反应体系中，阻聚剂的用量为甲基丙烯酸质量的0.01%‑0.5%，催化剂甲烷磺酸的用量为甲基丙烯酸质量的0.1%‑2%，甲基丙烯酸与2‑羟基‑4'‑(2‑羟乙氧基)‑2‑甲基苯丙酮摩尔比例为1:1‑1.2。阻聚剂是对羟基苯甲醚、对苯二酚或2－叔丁基对苯二酚，溶剂是甲苯、二甲基甲酰胺或四氢呋喃。本发明可聚合光引发剂可与光固化体系中的单体、树脂有较好的相容性，光照裂解后的碎片在固化膜中迁移率小，耐黄变,引发效果优良，可用于光固化涂料，油墨，胶粘剂等领域。本发明合成方法成本低，工艺简便，应用效果明显。
