| 摘 要： | 糊化淀粉经阳离子试剂醚化后再直接与丙烯酸钠(AA-Na)/丙烯酰胺(AM)接枝共聚,制得具有两性的淀粉接枝共聚物。并对淀粉的阳离子试剂醚化、淀粉与AA-Na/AM接枝共聚的接枝率、单体转化率、接枝效率及淀粉的糊化方式对产物性能的影响进行了研究。为工厂就地生产和应用两性淀粉接枝共聚物提供技术依据。

| Abstract: | Paste starch cationic etherification was used to graft copolymerization with sodium acrylate—acrylamide directly, a mpHoteric starch grafted copolymer was prepared. The effects of starch cationic etherification and starch gelatinization on the product properties, and the yield of sodium acrylateacrylamide grafting copolymerization were discassed. |
