LG MMA was founded in 1991 as a joint venture of LG Corp. and the prominent Japanese chemical company Sumitomo Chemical Co ,Ltd. and Japan Catalyst Inc. to localize methylmethacrylate (MMA) in Korea. This is to cope with increasing domestic MMA demand by producing MMA, which was dependent on imports totally at the time. Currently, LGMMA produces various monomers such as MMA, methacrylic acid (MAA), n-butyl methacrylate (n-BMA) and i-butyl methacrylate (i-BMA). We also produce various MMA base copolymers such as polymethylmethacrylate (PMMA) resin and poly(methylmethacrylate-co-styrene) (MS) resin etc.<br/><br/>In this talk, I will briefly introduce LGMMA and LGMMA R&D center. The LGMMA R&D center is involved in research and development related to PMMA. In particular, we are developing new application of existing PMMA grades, new special grade and new process, and improving existing process and PMMA grades. Recently developed and commercialized several PMMA products such as PMMA resin for coating which is used as an ink binder, and PMMA resin for electronic application which is used for polarizer protective film in LCD TV. In addition, research and development are continuously carried out to improve heat resistance and impact resistance, which are disadvantages of conventional PMMA.
