聚丙烯酸钠类高吸水性树脂的研究

Study of sodium polyacrylate with high hygroscopicity resin

采用反相悬浮聚合法合成高吸水性树脂。将丙烯酸(单体,水相)用氢氧化钠部分中和,然后与环己烷(溶剂,油相)共混,用水溶性的过硫酸钾做引发剂,N,N-亚甲基双丙烯酰胺做交联剂,在一定的反应温度和时间下,得到聚丙烯酸钠高吸水性树脂。

Using antiphase suspension polymerization to synthesize the high hygroscopicity resin. Added parts of propylene acid （monomers, water phase） with sodium hydroxide, and then added cyclohexane for co-mixing. Under the certain reaction temperature and time, taken the water-solubility ammonium persulfate as initiator and N, N-methylenebis acrylamide as crosslinker, finally the sodium polyacrylate with high hygroscopicity resin had obtained.
