WebMethyl Methacrylate Poly(methyl methacrylate) b.p. = 100°C Because of the excellent optical properties, weather resistance, light weight, impact and shatter resistance (compared to inorganic glass), dimensional stability, heat resistance, and processability, PMMA has many profound and diverse uses that affect our lives every day. WebPoly(methyl methacrylate) (PMMA) is usually obtained by the addition polymerization of methyl methacrylate (MMA) (Fig. 1). In the middle of the 1930s, ICI Acrylics (now Lucite International) invented the first commercial process, so-called acetone cyanohydrin (ACH) route, for producing MMA monomer.
