摘　　要：本文采用盐酸三甲胺和环氧氯丙烷制得阳离子醚化剂 ,在碱性条件下与淀粉反应来制备阳离子淀粉。阳离子淀粉在引发剂的作用下与丙烯酰胺发生接枝共聚反应。研究了某些聚合反应因素(引发剂浓度、pH值、反应温度、阳离子淀粉与丙烯酰胺比例 )对接枝共聚的接枝率、接枝效率和单体转化率的影响。Cationic starch is prepared in a three-neck flask where Xinjiang aboriginnal corn starch is reacted with the mixture of 3-chloro-2-hydroxy-propyl trimethy lammonium chloride and alkali catalyst under substantially dry reaction conditions. This paper also studies the effects of several factors(concentration of the initiator, pH value and reaction temperature and ratio of cationic starch to AM) on the grafting rate, grafting efficiency and ratio of monomer convertion.
