Description of MAA
Methacrylic acid, abbreviated MAA, is an organic compound. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents. Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate (MMA) and poly(methyl methacrylate) (PMMA). The methacrylates have numerous uses, most notably in the manufacture of polymers with trade names such as Lucite and Plexiglas. MAA occurs naturally in small amounts in the oil of Roman chamomile.

What is MAA?
Part I: Introduction
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is MAA which has developed particularly rapidly in recent years. Do you know about MAA?
The official answer: Methacrylic acid, an organic compound with the chemical formula C4H6O2, is a colourless crystal or transparent liquid with a pungent odour. It is soluble in hot water and soluble in most organic solvents such as ethanol and ether. Easily polymerized into water-soluble polymers. It is flammable and has the risk of burning when exposed to high heat and open flame.
What’s the application of MAA?
Part 2: In-depth development
Used as an organic reagent.
Used in the manufacture of coatings, insulating materials, adhesives, and ion exchange resins.
Important organic chemical raw material and intermediate for polymers. Its most important derivative, methyl methacrylate, is used to produce plexiglass for windows in aircraft and civil buildings, buttons, solar filters, and automotive light lenses; coatings with superior suspension, rheology, and durability properties; binders for bonding metals, leather, plastics and construction materials; and methacrylate polymer emulsions as fabric finishing agents and antistatics.
In addition, methacrylic acid is also used as a raw material for synthetic rubber.
