| 摘 要： | 以丙烯酰胺（AM）、阳离子单体二甲基二烯丙基氯化铵（DMDAAC）为原料，用分散聚合法合成了AM/DMDAAC阳离子共聚物。用IR谱图考察了在不同的分散体系中合成的共聚物，表明乙醇-H2O分散体系为3种体系中最佳的分散聚合体系；用TEM、粒度测定法等多种现代分析仪器和方法对乙醇-H2O分散体系合成的PDMDAAC-AM进行了分析表征。实验结果表明，乙醇-H2O分散体系合成的阳离子共聚物PDMDAAC-AM的粒度在纳米范围内，而且由于分散聚合体系本身是个乳状液体系，有利于反应的热交换，所以采用分散聚合法合理的解决了聚合反应中的散热问题，体现了分散聚合法的特点。

| Abstract: | Cationic copolymer acrylamide-dimethyldiallylammonium chloride P(AM/DMDAAC)] was synthesized from acrylamide(AM)and dimethyldiallylammonium chloride(DMDAAC)by dispersion polymerization.The structures of polymers synthesized in different systems of dispersion were determined with infrared spectroscopy.The results showed that ethanol-H2O was the best system of dispersion.The characteristics of PDMDAAC-AM were studied by means of various instrumental analysis techniques,including transmission electron microscope(TEM)and Zetasizer 3000HSA.The results showed that the particle size of cationic PDMDAAC-AM synthesized in the ethanol-H2O system of dispersion was within the range of nanometer,and the dispersion polymerization in the emulsion state was helpful to dissipation of reaction heat. |
