摘要: |
以丙烯酸,二甲胺,环氧氯丙烷为原料,通过曼尼希反庆制得两性离子单体,通过单体与丙烯酰胺的水溶液聚合,讨论其聚事的条件对转化率的影响,为提高分子量而采用沉淀聚合,并讨论沉淀聚合时的各条件对分子量的影响,最后测定 共聚物的阳离子度,并说明分子量和阳离子度对聚合物防膨性的影响。 |

Abstract: |
Amphoteric monomer is prepared with acrylic acid,dimethylamine,and chloro-ethanol by Mannich reaction.It got the regular that the monomer with acrylamide by free radical solution.In order to increase molecular weigh,it used precipitation copolymerization. |
Key words: amphoteric monomer,amphoteric polymer,solution polymerization,precipitation polymerization,cationic degree |
