聚丙烯酸盐高吸水树脂的合成

Synthesis of Super Absorbent Resin of Polyacrylic Acid Sodium Salt

以Span 80为分散剂,过硫酸钾为引发剂,N,N′-亚甲基双丙烯酰胺为交联剂,采用反相悬浮聚合法制备聚丙烯酸盐高吸水树脂,研究了丙烯酸中和度,引发剂、交联剂以及分散剂用量对聚合物吸水率的影响。

A super water - absorbent resin was synthesized by means of inverse suspension polymerization, in which the continuous phase was cyclohexane, dispersing agent was Span80, crosslinking agent was N, N' - methylene bis - acry-lamide and initiator was potassium persulphate. The influences including degree of neutralization of acrylic aicd, the amount of initiator,crosslinker、suspension agent on absorption capacity were studied.
