引言

甲基丙烯酸甲酯(简称MMA)是一种重要的有机化工原料，主要作为聚合单体用于生产其聚合物和共聚物，还可通过酯交换用于生产甲基丙烯酸高碳酯。甲基丙烯酸甲酯的主要下游产品聚甲基丙烯酸甲酯(PMMA)-有机玻璃是一种发展较早的重要热塑性塑料，具有极好的透明性、化学稳定性、耐候性等优良特性，广泛用于汽车、建筑、卫生洁具等方面，它可代替玻璃作为不易破碎的建筑材料。PM—MA 高分子材料适用于制造高级光学镜头、高级光学仪器透镜、高容量DVD 碟片片基材料、汽车尾灯灯罩、液晶显示器导光板等产品，具有良好的市场前景。另外，甲基丙烯酸甲酯还用于涂料、乳液树脂、粘合剂、PVC 树脂改性剂、聚合物混凝土、腈纶第二单体、纺织浆料、医药功能材料，离子交换树脂、纸张上光剂、纺织印染助剂、皮革处理剂、润滑油添加剂、原油降凝剂、木材和软木材的浸润剂、电机线圈的浸透剂、绝缘灌注材料和塑料型乳液的增塑剂等，用途十分广泛。

一直以来，甲基丙烯酸甲酯在人们日常生活中有不可或缺的作用，渗透于人们生活中的方方面面。甲基丙烯酸甲酯在药剂中主要用作粘合剂和溶剂。作粘合剂时,常添加适宜的过氧化物使其聚合。此外也用于制备丙烯酸醋树脂以及其他聚合物的单体。
