polymethyl methacrylate Chemical Properties

     Poly(methyl methacrylate) (PMMA) poly(methyl 2-methylpropenoate) is a thermoplastic and transparent plastic. 
     it is the synthetic polymer of methyl methacrylate. It is  commonly called acrylic glass, simply acrylic, perspex or plexiglas. Acrylic, or acrylic fiber, can also refer to polymers or copolymers containing polyacrylonitrile. It is brittle,so should becareful when loaded, especially under an impact force.
    polymethyl methacrylate ignites at 460 °C and burns, forming carbon dioxide, water, carbon monoxide and low molecular weight hydrocarbons, including formaldehyde.

polymethyl methacrylate History

    POLYMETHYLMETHACRYLATE,The material was developed in 1928 in various laboratories and was brought to market in 1933 by Rohm and Haas Company.
   

polymethyl methacrylate Uses

     PMMA or Acrylic is a versatile material and has been used in a wide range of fields and applications.It is often used as an alternative to glass, and in competition with polycarbonate (PC). polymethyl methacrylate is often preferred because of its moderate properties, easy handling and processing, and low cost.

polymethyl methacrylate Production

       Synthesis:PMMA is routinely produced by emulsion polymerization, solution polymerization and bulk polymerization. Generally radical initiation is used (including living polymerization methods), but anionic polymerization of PMMA can also be performed.To produce 1 kg of PMMA, need about 2 kg of petroleum.
