Itaconic Acid  (also called Methylene Succinic Acid)  is a white crystalline carboxylic acid obtained by the fermentation of carbohydrates. It is soluble in water, ethanol and acetone. Unsaturated double bond makes a conjugated system with carbonly group.

APPLICATIONS:

• Co-monomer to prepare acrylic fibers and rubbers, paint and coating, reinforced glass fiber, artificial diamonds and lens
• Additive in fibers and ion exchange resins to increases abrasion, waterproofing, physical resistance, dying affinity and better duration
• Water treatment system to prevent contamination by metallic alkali
• As binder and sizing agent in non-weaving fibers, paper and concrete paint.

The end applications of itaconic acid and its esters include in the field of co-polymerizations, plasticizers, lubricant oil, paper coating. carpets for better duration, adhesives, coatings, paints, thickener, emulsifier, surface active agents,  pharmaceuticals and printing chemicals.
