superabsorbent polymer

Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass.
Notes:
  1. The liquid absorbed can be water or an organic liquid.
  2. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1.
  3. Superabsorbent polymers for water are frequently polyelectrolytes.
