Multicomponent superabsorbent gel particles

摘要

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 covalently bound to at least one microdomain of the basic resin via an interfacial crosslinking agent. Blends of multicomponent superabsorbent gel particles with particles of a second water-absorbing resin, and improved diaper cores containing particles of the multicomponent superabsorbent gel particles also are disclosed.
