Abstract
This invention relates to fluid absorbent polymer compositions having the ability to absorb aqueous ionic fluids and water rapidly and efficiently. These fluid absorbent polymer compositions are prepared from fine base polymer particles which are ionically surface crosslinked and agglomerated into larger particles by the use of high energy mixing conditions. The fluid absorbent compositions of the invention find application in the preparation of absorbent articles such as diapers, sanitary napkins and incontinent devices.
