Acrylic plastic is apart of the synthetic plastic family made with one or more acrylic acids. The most common acrylic plastic is Polymethyl Methacrylate. PMMA is a tough, highly transparent material with wonderful resistance to ultraviolet radiation and weather. Acrylic plastic can be colored, molded, cut, and drilled. Like all plastics, acrylic plastics are polymers. A polymer is a material made up of many molecules, or parts, linked together like a chain. A polymer also has properties different than its component parts.
Methyl methacrylate is the basic molecule, or monomer, from which polymethyl methacrylate and many other acrylic polymers are formed. The chemical notion for this material is
CH 2 =C(CH 3 )
