PTFE or Telfron is a common commercial organic fluoropolymer obtained from the polymerization of tetrafluoroethylene. It was first synthesized by Roy Plunkett accidentally in New Jersey in 1938 (Plunkett, RJ, 1987). It gradually becomes an important industrial material due to its extraordinary properties of high corrosion resistance, good electrical insulation, good thermal insulation and low friction coefficient. Due to these properties it is widely used as gaskets in the chemical processing industry and tubes or tubing for laboratory uses. The low coefficient of friction also makes it a good lubricant. Properties of Tetrafluoroethylene PTFE is polymerized from the TFE monomer. TFE is made up of 2 carbon atoms and 4 fluorine atoms. The atomic orbitals of the two carbon atoms undergo sp2 hybridization individually with the 2 fluorine atoms and overlap with each other to give a planar structure. Because fluorine is a very electronegative element, TFE has very poor solubility in most solvents. The carbon-fluorine bonds are very stable in the compound, relatively, the pi bond in the carbon-carbon double bond is weaker and more reactive. The high polarity present in the structure also contributes to the value of the enthalpy change of TFE polymerization equal to 41.12 kcal per mole which is very exothermic (Gangal, SV, 1989). Polymerization Principle Generally, free radical polymerization is promoted by TFE which can be divided into 3 phases, namely initiation, propagation and termination.1. Initiation: The common initiator of free radicals is ammonium persulfate and disuccinic acid peroxide. (FA Bovey and FH Winslow, 1979) Free radicals are formed due to deco...... middle of paper ......tember 1952, http://www.freepatentsonline.com/2612484.htmlGeorge, They hate.
