Sodium polyacrylate, also known as waterlock, is a polymer with the chemical formula [-CH2-CH(COONa)-]n widely used in consumer products. It has the ability to absorb as much as 200 to 300 times its mass in water. Acrylate polymers generally are considered to possess an anionic charge. While sodium neutralized polyacrylates are the most common form used in industry, there are also other salts available including potassium, lithium and ammonium.

Applications

Acrylates and acrylic chemistry have a wide variety of industrial uses that include:

  • Polyacrylamide, a cationic charged polymer used in straight-chain form or can be co-polymerized with acrylic acid and other monomers. In cross-linked form, these blended co-polymers can yield specialty super absorbent polymers.
  • Polyacrylic acid
