Chemical of the Week -- Polymers

The free, unlinked amide groups, because they contain –NH 2 groups, can form hydrogen bonds with water. This gives the tiny cross linked sponges a great affinity for water. Polyacrylamide can absorb many times its mass in water. This property is useful in a variety of applications, such as in diapers and in potting soil.
