Polytetrafluoroethylene (PTFE) or teflon

Polytetrafluoroethylene (PTFE)

  • Polytetrafluoroethylene (trade name- Teflon), was accidentally discovered by Roy Plunkett (a Dupont chemist).
  • This is a polymer which has repeating chains of -(-CF₂-CF₂-)- in it.
  • It is an addition polymer of tetrafluoroethylene (CF₂= CF₂). It is obtained by heating tetrafloroethylene in a presence of catalyst at high pressure.

    Polytetrafluoroethylene.
  • Polytetrafluoroethylene is produced by the free radical mechanism.
  • It is resistant to many chemicals.
  • It is weather and UV resistant.
  • It is non sticky.
  • It appears to be quite slippery.
  • It has outstanding performance at extreme temperatures.
  • It is used as a non-stick coating for cooking pans and utensils.
  • Teflon is also used in curling irons and straighteners.
  • Teflon is also coated on the iron to quicken the heating up process.
  • Teflon is also used as artificial limb and body parts.
  • Teflon tape or plumber's tape is a polytetrafluoroethylene film tape commonly used in plumbing. Teflon tape looks like a regular tape but it is not sticky at all. Next

Determination of molecular weight of polymers by viscosity method.

Determination of molecular weight of polymers by viscosity method. It is a simple method for determining the molecular weight of polymers. Addition of polymers in the solvent increases the viscosity of the solvent, due to introduction of inhomogeneities by the polymers. If η₀ is the viscosity of the solvent and η is the viscosity of the solution at the same temperature, then the relative viscosity is given by Relative viscosity. Specific viscosity:  It is defined as the relative increase in viscosity and is given as Specific viscosity. Reduced viscosity: It is defined as the relative increase in viscosity per unit concentration (C) of polymer and is given as Reduced viscosity. Intrinsic viscosity: The reduced viscosity is dependent on concentration (C). If a graph is plotted between  reduced viscosity vs concentration then the extraplotation value when C=0 is called intrinsic viscosity. Intrinsic viscosity. Graph of reduced viscosity vs concentr

Polypropylene (PP)

Polypropylene (PP). Polypropylene (PP) is also known as polypropene. Polypropylene is made from the polymerisation of propylene gas in the presence of Zeiglar Natta catalyst or metallocene catalyst. Polypropylene. Thus propene (or propylene) is the monomer of polypropylene. Polypropylene is a highly flammable material. It is sensitive to microbial attacks, such as bacteria and mold. It exhibits excellent resistance to diluted and concentrated acids, alcohols and bases. Polypropylene is used to make lunch boxes, margarine containers, yogurt pots, syrup bottles etc. Disposable syringes is the most common medical application of polypropylene. Polypropylene rope and twine are very strong and moisture resistant very suitable for marine applications. Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats. Uses of Polypropylene. Questions on polypropylene; Q1) What is polypropylene? Ans) Polypropylene is a polymer of propylen

Difference between organic and inorganic polymers.

Difference between organic and inorganic polymers. Definition Organic polymers are the polymers that essentially contain carbon atom in the backbone. Inorganic polymers are the polymers that have no carbon atom in the backbone. Structure Most organic polymers have simple structures. Almost all inorganic polymers are highly branched and have complex structures. Electrical Conductivity In most of the aqueous solutions, organic polymers are typically poor conductors of electricity and heat. Inorganic polymers in aqueous solutions are good conductors of electricity, this is because they have high ability to ionise and this makes them better conductors. Flammability Organic polymers are flammable whereas inorganic polymers are nonflammable. Effect on nature Organic polymers are environmental friendly as these are biodegradable. Inorganic polymers are not environmental friendly as these are non biodegradable. Examples Organic polymers include polysaccharide
