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 by osmotic pressure method

Determination of molecular weight by osmotic pressure method. Osmotic pressure method is also called membrane osmometry. This method is widely used to determine the number average molecular weight of polymers. This method is based on the phenomenon of osmosis. If a pure solvent is separated from a solution through a semipermeable membrane, due to concentration (chemical potential) difference between the solvent and solution, the solvent will flow into the solution through semipermeable membrane. The pressure applied on the solution to completely stop the flow of solvent into it through semipermeable membrane is called osmotic pressure. The theory of osmotic pressure also applies to a solution of polymers. Ordinary solution obeys Van't Hoff equation i.e π=cRT/M Where π is osmotic pressure, c is concentration in mass per unit volume, R is gas constant, T is temperature and M is molar mass. The polymer solution are non ideal. Taking into account their deviation and us...

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 vi...
