Abstract: Multicomponent superabsorbent gel particles are disclosed. The multicomponent particles comprise at least one acidic water-absorbing resin and at least one basic water-absorbing resin. Each particle contains at least one microdomain of the acidic resin in contact with, or in close proximity to, at least one microdomain of the basic resin. Blends of multicomponent superabsorbent gel particles with particles of a second water-absorbing resin also are disclosed. Improved diaper cores containing particles of the multicomponent superabsorbent gel particles also are disclosed.

Abstract: Poly(dialkylaminoalkyl (meth)acrylamide)-based superabsorbent gels are disclosed. The superabsorbent gels either comprise a mixture of a poly(dialkylaminoalkyl (meth) acrylamide) polymer and an acidic water-absorbing polymer, like polyacrylic acid, or comprise a salt of a poly(dialkylaminoalkyl (meth)acrylamide) polymer. An improved method of preparing an N-(dialkylaminoalkyl) (meth)acrylamide monomer also is disclosed.

Abstract: Multicomponent superabsorbent gel particles are disclosed. The multicomponent particles comprise at least one acidic water-absorbing resin and at least one basic water-absorbing resin. Each particle contains at least one microdomain of the acidic resin in contact with, or in close proximity to, at least one microdomain of the basic resin. Blends of multicomponent superabsorbent gel particles with particles of a second water-absorbing resin also are disclosed. Improved diaper cores containing particles of the multicomponent superabsorbent gel particles also are disclosed.
