Question

Which is fully fluorinated polymer?

Answer 1

Hint: Polymers are the high molecular mass compounds obtained by joining repeating structural units regularly. The simple reactive molecules from which the repeating structural units are derived are called monomers. The use of polymers in the manufacture of toys, synthetic clothing materials, packaging bags, automobile tyres, plastic buckets, cups, and saucers, etc. has completely revolutionized the daily as well as the industrial scenario.
The giant molecules like DNA, chlorophyll, proteins, carbohydrates, etc. are regarded as macromolecules.
Chlorophyll is a macromolecule but is not regarded as a polymer because it does not contain a repeating unit.

Complete step by step answer:
Fully fluorinated polymers mean a polymer that contains only fluorine rather than other substituents.
Teflon or polytetrafluoroethylene (PTFE) is a fully fluorinated polymer.
It is prepared when tetrafluoroethylene is subjected to polymerization in presence of acetyl peroxide which gives rise to an additional polymer. The above reaction involved in this process is written below:

Another polymer that contains fluorine is Polymono Chlorotrifluoroethylene (PCTFE). Since it contains chlorine along with fluorine so it is not a fully fluorinated polymer. After discussing it we can conclude that Teflon is a fully fluorinated polymer.

Additional Information:
The polymerization reaction involved in the preparation of Teflon is addition polymerization.
In this type, the molecules of the same monomer or different monomers add together on a large scale to form a polymer. The monomer is unsaturated compounds like alkenes, alkadienes, and their derivatives. This type of polymerization leads to an increase in chain length or chain growth. The combination of monomers takes place through a free radical mechanism.

Note: Teflon is a chemically inert substance that is used as a material resistant to heat. It is resistant to being attacked by corrosive materials.
It is used as a non-stick coating on cooking utensils.
It is used as an insulator for making gaskets and valves.
