| 摘 要： | 以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、丙烯酸(AA)、瓜尔胶(GG)为原料,N,N-亚甲基双丙烯酰胺(NMBA)为交联剂,通过超声辐射合成AMPS/AA/GG三元共聚树脂,借助热重曲线(TG)对树脂的热降解特性进行分析。实验结果表明:在优化条件下,树脂的吸水率最大,而且树脂具有良好的耐热性能和保水性能;热分解动力学分析结果显示树脂热降解活化能为164.29 kJ/mol,lg A为13.84,反应级数n=1/6,树脂的热降解遵循44号随机成核和随后生长机理。

| Abstract: | Using 2-acrylamide-2-methylpropionic sulfonic acid (AMPS), acrylic acid (AA) and guar gum (GG) as raw materials, N, N-methyl bisacrylamide (NMBA) as crosslinking agent, a copolymer resin of AMPS/AA/GG was prepared by ultrasonic irradiation polymerization and the corresponding thermal degradation behavior was also studied by TG. The results showed that under the optinized condition, the water absorbency of the resinwas the largest and the resin had an excellent thermal stability and good retention ability. The activation energy, lg A and reaction order n were 164.29 kJ/mol, 13.84 and 1/6 respectively by kinetics methods and the thermal degradation process followed the random nucleation and subsequent growth mechanism. |
