阳离子型聚丙烯酰胺的合成及影响因素研究

Study on Synthesis of Cation-Polyacrylamide and Effecting Factors of Synthetic System

为合成一种高效阳离子聚丙烯酰胺絮凝剂,采用光引发聚合技术,以丙烯酰胺(AM)和二甲基二烯丙基氯化铵(DMDAAC)为单体进行聚合,检测所得聚合产物的性能,探讨光引发剂用量、反应单体的配比、单体总浓度等因素对合成体系的影响,利用红外光谱分析聚合产物的结构特征。

Acrylamide(AM) and dimethyl dially ammonium chloride(DMDAAC) are used as monomers to synthesize flocculant of Cation-polyacrylamide (CPAM) by photo-initiation method.Character of resulting copolymer is examined.Effecting factors of synthetic system,such as dosage of photoinitiator,proportion and bulk concentration of building units are discussed.Constitution of copolymer is characterized by infrared spectrum.
