MODIFIED SUPERABSORBENT POLYMER CONTAINING A FERTILIZER |
| 摘要 |
A modified superabsorbent polymer (SAP) comprises a SAP matrix and urea in the form of crystals that is integrated into the SAP matrix. The SAP matrix and the urea are interpenetrated. A method for producing the modified SAP may comprise a) preparing a mixture comprising at least one urea solution and at least one SAP, b) swelling the SAP in the mixture, c) crystallizing the urea in the mixture obtained upon completion of step b), d) recovering the modified SAP in the mixture, and e) optionally, forming the modified SAP recovered at step d). |
