| 摘 要： | An acrylic acid/kaoline powder superabsorbent composite with a water absorbency of the superabsorbentcomposite about 1/800 was synthesized by inverse-suspending polymerization reaction between acrylic acidmonomer and kaoline ultrafine powder. The influence of the dispersant agent on the configuration of theproducts in the inverse suspension polymerization is investigated. The influences of the kaoline powder.cross-linker, initiator, neutralization degree and the volume ratio of oil to water phase on the water absorben-cy of the superabsorbent composites are discussed in the paper.
