以丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)、二甲基二烯丙基氯化铵(DMDAAC)为单体原料,采用水溶液聚合技术制备了粉末型阳离子三元聚合物P(AM/DMC/DMDAAC).采用红外光谱、核磁共振和热重分析对所制备阳离子聚合物进行了结构和组成表征,并利用电导率仪和布氏黏度计对其溶解性及其溶液黏度进行了测定.结果表明:合成的产物为P(AM/DMC/DMDAAC),具有良好的热稳定性和溶解性.三元聚合物的表观黏度随着聚合物质量浓度的增加先减小后增加,随剪切速率的增加而下降.在不同的外加盐溶液里,三元聚合物溶液表现出明显的反聚电解质行为.

The pulverous cationic terpolymers P (AM/DMC/DMDAAC) were prepared by aqueous solution copolymerization with acrylamide (AM) , (2-methacryloyloxyethyl) trimethylammonium chloride (DMC) and dimethyldiallylammonium chloride (DMDAAC) as the raw materials. The cationic copolymers were characterized by means of Fourier Transform Infra-Red,~1H-NMR and Thermogravimetry. The solubility and viscosity of terpolymer were measured by means of Conductivity Meter and Brookfield Programmable DV- II + Viscometer, respectively. The results indicate that the product is the terpolymer of AM, DMC and DMDAAC, which has better thermal stability and solubility. With increasing the terpolymer mass concentration, the apparent viscosities of terpolymer solution first decrease and then increase, however, the apparent viscosities decrease with increasing shear rate. In the different salts solutions, the terpolymer solution exhibits obvious antipolyelectrolyte characteristics.
