Claim 79:
80. The method of claim 79, wherein the extruded absorbent pellets: (1) are each comprised of a gel that forms a gel whose viscosity increases over time when wetted with water, (2) swell by expanding in volume at least 5% when wetted with water, (3) are substantially retrogradation proof at room temperature, (4) are cooled immediately upon extrusion at a coolant rate of at least 15 degrees Fahrenheit per second for at least two seconds after extrusion, (5) are dried by reducing a moisture content of the extruded absorbent pellets by at least 1% by weight from an initial moisture content of the extruded absorbent pellets upon exiting the extruder during the extruding step within five seconds of the extruded absorbent pellets exiting the extruder, and (6) form a clump when wetted with water without the presence of any agglutinating agent additive or clumping agent additive other than the water-soluble binder.
