摘要:

本文以丙烯酰胺（ＡＭ）、丙烯酸（ＡＡ）和阳离子单体ＡＣ为原料，采用溶液聚合法合成了阴阳非离子三元共聚物ＬＯ－１，评价了该三元共聚物的基本性能。结果 表明：ＬＯ－１三元共聚物具有良好的抗剪切、抗盐能力和较好的耐温性与热稳定性。以三元共聚物为基液配制的冻胶具有良好的粘弹性，可望作为选择性堵剂使用。

Abstract:

An cationic-anionic-nonionic terpolymer LO-1, is synthesized in the laboratory. The performance evaluation shows the terpolymer is fairly good to tolerance of shear and sodium salts, and also good to temperature resistance and thermostability. The gelling
