Methyl methacrylate (MMA) is a clear, colorless liquid with a slight acrylic or fruity odor. It's
comprised of a polymerizable methacrylate functional group on one end and a reactive ester group
on the other end. It is slightly miscible with water, soluble in most organic solvents and has
relatively low volatility. Its vapor is heavier than air. It copolymerizes readily with a wide variety of monomers.
The added ester group imparts properties such as durability, strength, transparency
and an elevated Tg.

Applications:-
Methyl methacrylate can be homopolymerized into polymethyl methacrylate (PMMA), and
extruded or cast into a variety of products. These products exhibit transparency, high impact
strength and UV stability.
Methyl methacrylate copolymerizes readily with a wide variety of monomers. The resulting polymer
chains bear pendent ester groups that impart the following important properties to the polymer
products.
• Impact strength
• Weather resistance
• Crosslinking sites, ester group reacts readily with isocyanate, anhydrides and epoxy
resins
• Corrosion, fogging, and abrasion resistance, as well as contribute to low odor, color, and
volatility.
• Methyl methacrylate monomer is also used in the manufacture of paints, coatings,
adhesives and binders, packaging materials, inks and concrete additives as well as
finding use in variety of medical applications.
