Poly(methyl methacrylate)

also: PMMA, brand names: Plexiglass, Acrylite, Lucite, Perspex and many others.

Chemistry: Poly(methyl 2-methylpropenoate).
It is often technically classified as a type of glass hence its occasional historic designation as acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate.
PMMA is an economical alternative to polycarbonate (PC) when tensile strength, flexural strength, transparency, polishability, and UV tolerance are more important than impact strength, chemical resistance and heat resistance. PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate. It is often preferred because of its moderate properties, easy handling and processing, and low cost.

Implant: Methacrylate polymers are used extensively in medical (e.g. bone stabilization, eye) and dental applications.
