What is the Structure of a Hydrogel?\r
Hydrogels are cross linked polymers that have hydrophillic groups.\r
They are often polymers containing carboxylic acid groups. One\r
common polymer used to make hydrogels is sodium polyacrylate.\r
The chemical name for this polymer is poly(sodium propenoate).\r
