摘要：

本文叙述了丙烯酰胺，环氧氯丙烷，二甲胺通过三组份不对称缩合反应制备Ｎ—（３—二甲胺基、２—羟基）丙基丙烯酰胺盐酸盐，即ＤＭＡＰＡ，并同丙烯酰胺进行水溶液自由基共聚合，获得-定阳离子度的阳离子聚合物。对该聚合物作了红外光谱图，确认聚合物具有正氨离子的结构。并用此阳离子聚合物进行粘土防膨及絮凝性评价，实验表明，不同阳离子度，不同分子量的该阳离子聚合物皆具有良好使用性能。

关键词: DMAPA, 自由基共聚合, 防膨率, 阳离子度

Abstract:

This paper describes the preparation of N N dimethyl hydroxyetbyl acrylamide (DMAPA) with acrylamide, epicholorohydrin and dimethylamide by their non symmetrical condensation reaction and the synthesis of cationic copolymers of different cationic degree by its radical copolymerization with acrylamide in aqueous solution. Besides the cationic nitrogen in copolymer is verified with IR spectrum and the clay stabilizing and floculating properties of the copolymer are evaluated. The experiments show that copolymers of different cationic degree and molecular weight have good applied properties.

Key words: DMAPA, Radical copolymerization, Swelling inhibiting rate
