    摘要: The invention relates to hydrophilic superabsorbent polymer comprising a) from about 55 to about 99.9 wt.% of polymerizable unsaturated acid group containing monomers; b) from about 0.001 to about 5.0 wt.% of internal crosslinking agent; c) from about 0.001 to about 5.0 wt.% of surface crosslinking agent applied to the particle surface; and d) wherein the composition has a degree of neutralization of more than about 20%, and from about 20 mole % to about 75 mole % of the unsaturated acid group containing monomers are neutralized with a first neutralizing agent, and from about 5 mole % to about 40 mole % of the unsaturated acid group containing monomers are neutralized with a second neutralizing agent; at a temperature of about 75'C or less. Such hydrophilic superabsorbent polymers have an Absorption Time of about 5+10 a 2 minutes or greater, where a is the mean particle size of the superabsorbent material in millimeters, a capacity of about 15 g/g or greater, a Drop Penetration Value of about 2 seconds or less, and a 1/2 Float Saturation of 50% or less.

    摘要: A fluid dispenser formed of a bottle for housing the fluid, a discharge mechanism for discharging fluid from the bottle, and a protrusion that is connected to and extends from the bottom of the bottle. The protrusion has a diameter that is smaller than the diameter of the bottom wall of the bottle. The bottle is capable of standing upward on a horizontal surface without the use of a separate base or mount when the protrusion extends into an aperture in the horizontal surface such that the bottom wall of the bottle rests on the horizontal surface.
