| 摘 要： | 采用黄原胶(XG)为基体,丙烯酸(AA)为接枝聚合单体,环己烷为连续相,过硫酸钾为引发剂,利用反相悬浮聚合法合成了XG-g-PAA高吸水性树脂。研究了丙烯酸与黄原胶质量比、引发剂(KPS)用量、交联剂(NMBA)用量、丙烯酸中和度和聚合反应温度等因素对树脂吸水率的影响。利用傅立叶变换红外光谱仪(FTIR)、扫描电镜(SEM)和热重分析仪(TGA)对产物进行了表征。结果表明,丙烯酸与黄原胶发生接枝共聚,在最佳工艺条件下制备的XG-g-PAA高吸水性树脂具有良好的吸水和抗盐性能,高温保水性能提高,对蒸馏水的吸水率为845 g.g-1,对质量分数0.9%的NaCl水溶液的吸水率为96.3 g.g-1,接枝率达126.5%,接枝效率达82.6%。
