Superabsorbent polymers having a slow rate of absorption |
| abstract |
The present invention relates to a superabsorbent polymer having a slow absorption rate and a method for preparing the same. The superabsorbent polymer has a slow rate of absorption, crosslinks with the metal of the covalent crosslinker and the polyvalent metal coordination compound, comprises metals of the coordination compound that are essentially uniformly distributed throughout the polymer, and has an absorption rate index of at least 5 minutes. . According to the invention, the rate of absorption is achieved by polymerizing monomers in the presence of a covalent crosslinker and a polyvalent metal coordination compound under conditions in which a polymer comprising a reversible cationic crosslinker is formed and the metal is essentially uniformly distributed throughout the polymer particles. Produces slow water swellable, water insoluble polymer particles. |
