| Abstract: | Super absorbent resin was a three dimensional network polymer, which was electrolyte. It can absorb several hundred even more than thousand times of water as much as its own weight, owning to its high capacity for absorbing water, high capacity of water retention under pressure. Absorbing water mechanism of super absorbent resin was studied by thermodynamic theory of Flory Huggins and thermodynamic theory of solution, and macromolecular structure. |
