Application

Itaconic acid (IA) can be used:
  • As a comonomer in the polymerization of polyacrylonitrile (PAN) to promote the thermo-oxidative stabilization of polymer.
  • In combination with acrylamide to form (poly[acrylamide-co-(itaconicacid)]) to synthesize biodegradable superabsorbent polymers.
  • To synthesize biobased polyester composite in fabric industry.
