The present invention relates to a particulate superabsorbent polymer composition which absorbs water, aqueous liquids, and blood, and a process to make the superabsorbent polymers, wherein a superabsorbent polymer is surface treated with a neutralized multivalent metal salt solution having a pH value similar as that of human skin. The present invention also relates to particulate superabsorbent polymer composition having high Gel Bed Permeability and high Absorbency Under Load.

Particulate superabsorbent polymer composition having improved performance properties

The present invention relates to absorbent compositions which exhibit swelling, deswelling, and reswelling behavior. More specifically, absorbent compositions of this invention swell and absorb fluids after exposure to aqueous fluids, deswell and release fluids from the swollen absorbent compositions, and may also reswell and absorb fluids. The swelling-deswelling-reswelling behavior allows enhanced liquid distribution in absorbent composites.

Superabsorbent polymer compositions having a triggering composition

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&#x2014;O bond. The present invention further relates to an absorbent article that includes such particulate superabsorbent polymers.

Superabsorbent polymer having a capacity increase

The present invention relates to absorbent articles that include absorbent compositions which exhibit swelling, deswelling, and reswelling behavior. More specifically, absorbent compositions of this invention swell and absorb fluids after exposure to aqueous fluids, deswell and release fluids from the swollen absorbent compositions, and can also reswell and absorb fluids. The swelling-deswelling-reswelling behavior allows enhanced liquid distribution in absorbent composites and absorbent articles.

Absorbent articles comprising absorbent materials exhibiting deswell/reswell

Solution blending of masterbatch of cationically functionalized polyvinyl acetate copolymer/silicate nanocomposite where the silicate is substantially exfoliated, and ethylene-vinyl acetate copolymer (EVA), produces product of increased tensile strength and Young's Modulus compared to neat EVA and reduced flammability compared to neat EVA. The product can be injection molded or compression molded or extruded without loss of these advantages.
