摘要： Described herein are superabsorbent polymers that are made of copolymers of charged monomer and neutral monomers, where the neutral monomers are alkyl or aryl end-capped neutral and hydrophilic monomers that lack free hydroxyl groups and have a water solubility of at least 200 mg/mL. The copolymer-based superabsorbent polymers have significantly improved absorbency under load. The compositions and methods described herein are useful in a variety of absorbent products.

摘要： Superabsorbent polymers are made of copolymers including a major portion of low molecular weight monomers each individually including a backbone and a charged moiety, a minor portion of high molecular weight monomers each individually including a backbone and a charged moiety, and optionally a crosslinker. The copolymer-based superabsorbent polymers have significantly improved absorbency under load.

摘要： Described herein are superabsorbent polymers that are made of copolymers of multiple charged monomers, where the charged moieties of different charged monomers have different distances from copolymer backbones. The copolymer-based superabsorbent polymers have significantly improved absorbency under load. The compositions and methods described herein are useful in a variety of absorbent products.
