Poly (Methyl Methacrylate)

                    

• A transparent thermoplastic which is an ester of methacrylic acid belongs to acrylic family of resins.
• A strong and lightweight material possess good impact strength higher than glass and filters UV lights.
• PMMA, the most common methacrylic polymer, is made into sheets by one of three methods; batch cell, continuous or extrusion.
• It has been sold under different names such as Plexiglas, Lucite, Perspex, Oroglas, Altuglas.
• Polymerization Mechanisms of producing PMMA are emulsion polymerization, solution polymerization and bulk polymerization.
