摘要：
Superabsorbent particles having less than 1000 ppm non-solvent, a median size of from about 50 to about 2,000 micrometers, and containing nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers are provided. The superabsorbent particles exhibit a Vortex Time of about 80 seconds or less.
