摘要
采用水溶液聚合方法，使用新型低温氧化还原复合引发体系，制备出相对分子质量大于1．0×10^7，溶解时间小于2h的高分子量耐温抗盐AM／AMPS二元共聚物P（AM-co-AMPS）。热重分析表明，P（AM-co-AMPS）共聚物较PAM均聚物具有更好的热稳定性。研究了胶粒后处理过程中的干燥温度、干燥时间对共聚物性能的影响，结果表明，干燥温度在70～90℃，干燥时间3h，对共聚物溶解性和分子量无明显影响。
The temperature resistance and salt tolerance acrylamide/2-acryamido-2-methyl propane sulfonic aid copolymer （P （AM-co-AMPS）） was synthesized using low temperature oxidation-reduction complex initiation system by aqueous solution polymerization. The molecular weight of the eopolymer was more than 1.0× 10^7 and the dissolving time was less than 2 hours. The research of the copolymer by TGA showed the copolymer P （AM- co-AMPS） had more excellent stability than the PAM. The drying temperature was between 70-90℃ and drying time was less than 3 hours, the quality of the copolymer, such as resolving time and degradation of molecular weight, had no obvious change.
