8 Polymethyl Methacrylate: PMMA Saijah Williams Mia Rodie

9 History and Markets Discovered in 1877 by Fittig and Paul

10 Uses and Properties 1972 Olympic Stadium- Munich, Germany (pontiacgrandprix.net) Edge-lighting.com Headlights made of PMMA Lighting Applications of PMMA LG LCD television

11 Polymer Chemistry PMMA is made of methyl methacrylate. PMMA is most commonly polymerized through free radical polymerization. The application of PMMA traces back to the type of polymerization used. Type of PolymerizationApplication BulkPlexiglas® SolutionAdhesives, paint resins SuspensionPMMA beads EmulsionPaper coating agents, paper processing agents, textile binders

12 Raw Materials and Production Process Hydrogen Cyanide Acetone Methyl formate Methyl methacrylate methyl a- hydroxyisobutyric Methyl formate a- hydroxyisobutyric acid amide Hydration of acetonecyanhydrin AcetonePrussic acid

13 Reactor Design Goal: 100 sheets of Plexiglas® per day Amount of PMMA per year: 800 metric tons Amount of time per batch: 5.6 minutes Equation 1 VariableMeaning K i, K p, K t Rate constants pPolydispersity [M]Concentration of monomer [I]Concentration of initiator
