  • SUPERABSORBENT POLYMER HAVING FAST ABSORPTION
    Publication number: 20150283284
    Abstract: The present invention relates to a particulate superabsorbent polymer composition having fast absorption and a method of making the particulate superabsorbent polymer comprising a monomer solution comprising a foaming agent and a mixture of a lipophile surfactant and a polyethoxylated hydrophilic surfactant wherein the particulate superabsorbent polymer composition has a mean particle size distribution of from 300 to 500 ?m and a vortex time of 30 to 60 seconds. The present invention further includes particulate superabsorbent polymer compositions surface treated with other components. The present invention further includes absorbent cores and articles including the particulate superabsorbent polymer compositions.
