Abstract

Described herein is an absorbent article having an absorbent core. The absorbent core includes a superabsorbent polymer material and a superabsorbent polymer immobilizing material. The superabsorbent polymer immobilizing material includes from about 20% to about 70% of a first polymer and from about 30% to about 80% of a second polymer. The superabsorbent polymer immobilizing material has a Shear Viscosity at 10 (1/s) at 230° C. of from about 300 mPa·s to about 10,000 mPa·s.
