Polymethylmethacrylate‚ or PMMA for short‚ is a polymer consisting of the monomer methyl methacrylate that has been around since the 1930s1. PMMA is a polymer that has a high impact strength‚ is scratch and shatter resistant‚ and is relatively lightweight1. Because PMMA can also be formed into a transparent thermoplastic and has a glass transitions temperature of 130oC‚ this polymer served as a glass substitute in its early uses1. Other beneficial characteristics of Polymethylmethacrylate include
