分散剂对三元共聚反相悬浮聚合法合成高吸水性树脂的影响

Effect of dispersion agent on Inverse Suspension Copolymerization of Acrylic Acid and Acrylamide and 2-Acrymido-2-Methypropane Sulfonic Acid for High Water Absorbency Resin

以丙烯酸、丙烯酰胺、2 丙烯酰胺 2 甲基丙磺酸为原料 ,过硫酸钾为引发剂 ,N ,N 亚甲基双丙烯酰胺为交联剂 ,环己烷为连续相 ,水为分散相 ,用反相悬浮聚合法合成了一系列高吸水性树脂 ,考察了分散剂种类、用量、混合分散剂。

A series of high water absorbency resins was synthesized by means of inverse suspension polymerization with acrylic acid (Ac) and acrylamide (Am) and 2 acrylamido 2 methylpropane sulfonic acid (Amps) as raw materials, potassium persulfate as initiator, N,N methylenebisacylamied (Bis) as crosslinker, cyclohexane as continuous phase and water as dispersed phase. The effects on the physical properties and water absorption ability were studied with different dispersion agents and amounts, mixed dispersion agents and anti adhesion agents.
