Surface-crosslinked superabsorbent polymer particles (SAP) having clay near the SAP surface have been disclosed. This clay is provided to the SAP particles during surface cross-linking, essentially reducing the formation and recirculation of SAP microparticles, and improved liquid uptake rate and improved liquid permeability in swollen SAP particles. SAP particles are provided. Diaper cores and absorbent products containing surface-crosslinked SAP particles have been disclosed. |
