Toshio Hayashi1, Kenji Ishikawa1, Makoto Sekine1, Masaru Hori1, Naoto Kodama1, Hirotaka Toyada1 (1.Nagoya Univ.)

Keywords:Teflon, PTFE, polymerization

PTFE was accidentally discovered on April 6 , 1938. Dr. Roy J. Plunkett, working with gases related to C2F4 refrigerants. However, the synthetic mechanism have not been discussed in detail. We examined this subject by using computational chemistry method, and found PTFE was produced by electron attachment and subsequent polymerization.
