Transcript of Poly(methyl methacrylate)
(PMMA) A transparent thermoplastic
Lightweight and shatter-resistant
Acrylic glass under the brand names:
Synthetic polymer of methyl methacrylate
Alternative to glass and polycarbonate Production Obtain monomer substance: methyl methacrylate * * Methyl methacrylate Organic compound with formula
Formed from acrylic acid
Methyl ester of methacrylic acid (MMA)
A clear liquid substance
Other uses: methylmetacrylate-butadiene-styrene (MBS), polyvinyl chloride (PVC)

Propylene Free Radical Polymerization:
Bulk Where From Synthesis [CH2C(CH3)(CO2CH3)]n The first acrylic acid was created CH2=CHCO2H Methacrylic acid is formulated Ferdinand Redtenbacher oxidized acrolein with aqueous silver oxide and isolated acrylic acid The reaction between methacrylic acid and methanol results in the ester, methyl methacrylate (MMA). German chemists Fittig and Paul discover the polymerization process that turns methyl methacrylate into polymethyl methacrylate German chemist Otto Rohm, of "Rohm & Haas", patented and registered the brand name Plexiglas. World War II Acrylic glass was used for
windshields, canopies, and gun turrets of airplanes Today PMMA is used in a wide variety of objects. It is easily made and affordable. Facts The monomer methyl methacrylate is considered toxic to human beings It is banned in Canada, 30 states in the US, New Zealand, and Australia Properties Lightweight
