Abstract
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.
