Polytetrafluoroethene polytetrafluoroethylene History PTFL was accident entirelyy created by Roy Plunkett of kinetic Chemical Company in 1938. Plunkett was trying to create a new refrigerant when the fluoroethene he was using polymerized in its reposition container. It was patented by energising Chemicals in 1941 and Teflon became a registered trademark in 1944. It was first gear sold commerci on the wholey in 1946. In 1950 DuPont had acquired full lunacy of Teflon and was producing over a million pounds per year. http://www.nationmaster.com/ encyclopaedia/Polytetrafluoroethene to the highest degree the Monomer: The monomer which makes up the polymer of polytetrafluoroethene, or Teflon, is called tetrafluoroethene. The monomer itself is serene of an ethene speck which has had all of its hydrogen atoms replaced by atomic number 9 atoms. How Its Made: Because Teflon is synthesized through and through with(predicate) the addition polymerization process, it undergoes the terce stages; initiation, propagation, and termination. After all of the tetrafluoroethene has been created through a series of heterotaxy reactions, its carbon-carbon double bail tie breaks open, making the monomer available to truss with ii other molecules. The droll electrons can now speck with another Teflon monomer at either end if the low-toned double bond. As the monomers think together, the chain propagates.
The chain egress is terminated when any dickens unpaired electrons ends combine, forming a contact lens between the two chains. sane Properties: Teflon is a whiteness warm at humour temperature, with a density of active 2.2g/cm3 and a melting show of 327° C (620.6° F). The coefficient of friction is 0.1 or less, making it the second last-place of any known solid material. Teflons enemy to van der Waals forces means that is the nevertheless known surface to which a gecko cannot stick. Teflon is also employ in insulating cables due to its brainy dielectric properties. Intermolecular Forces: In the Teflon polymer, the absence of the carbon-hydrogen bonds and the complaint of the...If you want to get a full essay, order it on our website:
