| 摘 要： | 在甲基丙烯酸二甲氨基乙酯氯甲烷盐(M_1)与丙烯酰胺(M_2)的水溶液共聚合中,研究了氧化还原-偶氮化合物复合引发剂的作用机理。测得54℃下两种单体的竞聚率为1.54(γ_1)和0.30(γ_2)。阳离子共聚物经~1H-NMR表征,证实有可能根据δ1.15和2.19ppm处两个共振峰确定共聚物的组成。

Copolymerization of Methyl Chloride Salt of Dimethylaminoethyl Methacrylate with Acrylamide and ~1H-NMR Characcterization of the Cationic Copolymers |
| |
| Abstract: | In the copolymerization of methyl chloride salt of dimethylaminoethylmethacrylate(M_1)with acrylamide(M_2)induced by redox-azo-compound complexinitiator in aqueous solution,the roles played by the complex initiator wereinvestigated.The reactivity ratios of the two monomers at 54℃ were 1.54(r_1)and 0.30(r_2).The cationic copolymer was characterized by ~1H-NMR.It isproved that its composition can be determined according to two resonance peaksat δ 1.16 and 2.19ppm. |
