【摘要】 采用水溶液聚合,以JL为交联剂,部分中和的丙烯酸、丙烯酰胺为单体,制成交联型耐盐高吸水性聚合物。正交实验确定了合成的最佳条件,并评价了合成产品的性能。研究结果表明,反应时间30 min,丙烯酸中和度70%,丙烯酰胺用量5 g,交联剂质量分数0 02%时,得到的聚合物的吸水率可达到150 g/g。更多还原

【Abstract】 Polymer with super water absorbing capacity was synthesized using JL as crosslinker,partly neutralized acrylic acid and acrylamide as main monomers by water solution polymerization.The optimum conditions for synthesis were determined by orthogonal test and the properties of synthesized product were evaluated.The result showed that water absorbing capacity of the polymer synthesized under the optimum conditions such as reaction time of 30 min ,neutralization ratio of 70%,the dosage of acrylamide 5g,the content of JL crosslinker 0 02% could be up to 150 g/g.更多还原
