Itaconic Acid
CAS Number: 97-65-4
Itaconic acid (IA) is a bio-based, bifunctional unsaturated dicarboxylic acid monomer produced by fermentation of sugars. It provides both vinyl polymerizability and two carboxyl groups for crosslinking, adhesion, and hydrophilicity enhancement. IA is an important green alternative to petrochemical monomers in SBR latex, acrylic emulsions, and superabsorbent polymers.
