Abstract:
The present invention relates to a particulate superabsorbent polymer comprising a monomer and an internal crosslinker agent wherein the particulate superabsorbent polymer has a Centrifuge Retention Capacity Increase of 2 g/g or more as set forth herein in the Centrifuge Retention Capacity Increase Test. The present invention further relates to a superabsorbent polymer comprising an internal crosslinker agent comprising a silane compound comprising at least one vinyl group or one allyl group attached to a silicon atom, and at least one Si—O bond. The present invention further relates to an absorbent article that includes such particulate superabsorbent polymers.
