Question

Which of the following is a chain growth polymer?
A.) Teflon
B.) Nylon-6,6
C.) Nylon-6
D.) None

Answer 1

Hint: Chain growth polymer is also known as addition polymer. The classification of the polymers is done on the basis of their formation. In this case too, we can determine the chain growth polymer, depending on the reaction of its formation.

Complete step-by-step answer:
Chain growth polymer is a polymer which is formed when molecules of the same monomer or different monomers add together on a large scale to form the polymer.

Teflon is a chain growth polymer as the molecules of tetrafluoroethylene (monomer) simply add together to form the polymer.
Hence Option A is the correct answer.

Additional Information:
We should know that Nylon 6, 6 is synthesized by polycondensation of hexamethylenediamine and adipic acid.

Nylon 6 is produced by ring-opening chain growth polymerization of caprolactam in the presence of water paper and an acid catalyst at the melt.

Teflon is used as a non-stick coating for pans and other cookwares. It is non reactive partly because of the strength of carbon fluorine bonds and so this is often used in containers and pipework for reactive and corrosive chemicals.
Nylon can be used for clothing. In industries it is used for parachutes, threads and tents. It is also used to make a fish net. Nylon can also be used as plastic in manufacturing machine parts.

Note: Chain growth polymerization is a polymerization technique where unsaturated monomers and molecules add on to the active site on a growing polymer chain one at a time. There are a limited number of these active sites at any moment during the polymerization which gives this method its key characteristics.
