摘要
对不加引发剂和无氮气保护情况下采用超声辐射技术制备高吸水树脂进行研究。以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为单体,N,N’-亚甲基双丙烯酰胺(NMBA)为交联剂,在不加引发剂和无氮气保护下,利用超声辐射技术合成PAMPS高吸水树脂,并对合成条件进行优化,得到了高吸水树脂的最佳工艺条件:单体AMPS质量分数[M]为35%,交联剂NMBA质量分数[C]为0.03%,单体中和度N为60%,并借助FT-IR和偏光显微镜对其结构及表面形态进行了表征。结果表明,树脂吸水过程符合一级动力学,在该反应条件下树脂的吸水倍率为1163g/g,吸盐倍率也达到76g/g。
Using 2-acrylamido-2-methylpropanesulfonicacid （AMPS） as monomer, N, N ＇-methylne-bisacrylmide （NMBA）as crosslinker, poly（2-acrylamido 2-methylpropanesulfonicacid）（PAMPS）was prepared using ultrasonic irradia- tion techniques without initiator and nitrogen atmosphere. The optimized polymerization conditions were obtained hy combi- ning orthogonal design and single-factor experiments as follows： mass concentration of monomer was 35 % and mass con centration of crosslinker compared to the amount of monomer was 0.1 % and neutralization degree was 60 % The molecular structure and surface shape of resin were characterized by FT-IR and microscope analysis. The results showed that the ab- sorbeneies of PAMPS were 1163g/g and 76g/g in distilled water and 0.9 % NaC1 under optimized conditions, respectively. The absorbing kinetics of resin followed first order kinetics equation.
