摘　　要：以玉米淀粉、甲基丙烯酰氧基乙基三甲基氯化铵和丙烯酰胺为主要原料,通过自由基共聚反应合成了阳离子淀粉。通过控制淀粉的用量、阳离子单体和丙烯酰胺的配比,合成出一系列阳离子淀粉,利用红外光谱及核磁共振谱对其进行了表征,并使用所合成的阳离子淀粉作为纸张增强剂,研究了共聚阳离子淀粉对纸张的增强作用。In the paper, the cationic starch was synthesized with cornstarch methacryloyloxyethyl trimethylammonium chloride and acrylamide by radical copolymerization, A series of cationic starches were synthesized by varying the amount of the starch and the ratio between DMC and AM, The Cationic starches were characterized and analyzed by IR and ^13 C-NMR. The reinforcing effects of the cationic starch on eucalyptus pulp were studied
