乙烯基甲醚作用

乙烯基甲醚又名甲氧基乙烯、甲基乙烯醚、乙烯基甲基醚，属于有机化合物，有麻醉作用，常温下为无色易燃气体，有特殊气味，易液化。分子量58.08。结构简式：CH2=CH—O—CH3。熔点-123℃。沸点8℃。相对密度0.7694(5.7/4℃)。折射率1.3947。闪点-51℃。溶于乙醇、乙醚，难溶于水。有甜味。容易聚合，因此在成品中常加入阻聚剂。可由乙炔与甲醇在氢氧化钾作用下，发生乙烯基化反应制得。乙烯甲醚和其它单体发生共聚来合成涂料、高分子材料、粘结剂、增塑剂以及聚苯乙烯树脂等的改进剂等。乙烯基甲醚可与马来酸酐共聚而得的水溶性树脂聚乙烯基甲醚-马来酸酐共聚物粘合剂。常温下外观为白色粉末，溶于温水或冷水，和乙二醇、胺类及某些无机盐反应而凝胶化，成为水不溶物，有较高的极性，能粘接橡胶、钢、铝、聚苯乙烯和硝化纤维素等。乙烯基甲醚经离子聚合再溶于水或有机溶剂而得聚乙烯基甲醚粘合剂，本品可用于粘接橡胶、铝、钢、聚苯乙烯、硝化纤维素及玻璃纸。
