Quick Summary

Methyl methacrylate (MMA) is a volatile, flammable liquid with the chemical formula C5H8O2. It readily polymerizes, meaning its molecules can link together to form larger structures.12

MMA is primarily used as a monomer, the building block for polymethyl methacrylate (PMMA). PMMA is a transparent, rigid plastic often used as a substitute for glass. It is known by trade names such as Plexiglas, Lucite, and Perspex.12

The production of MMA involves several steps, often starting with propylene derived from crude oil. This process ultimately yields MMA, which is then polymerized to create PMMA. PMMA's properties, including its near-perfect transmission of visible light and durability against UV radiation and weather, make it suitable for applications like shatterproof windows, aircraft canopies, and optical fibers.2
