Question

Name the process by which nylon \[ - 6,6\] is obtained?

Answer 1

Hint: We need to know that nylon- \[ - 6,6\] is a kind of nylon or it is a polyamide. And these are made up of mainly two monomers. And these monomers contain six carbon atoms. Here each of the polymer chains contains two forms of carbon atoms. The nylon \[ - 6,6\] is a type of synthetic polymer. And this synthetic polymer has good strength and is semi – crystalline. These nylon \[ - 6,6\] are mainly used to prepare cords, carpet etc.

Complete answer:
We need to remember that the nylon\[ - 6,6\]is prepared by using Hexamethylenediamine and adipic acid by condensation polymerization reaction or otherwise known as polycondensation reaction. And this process is a step- growth polymerization. When the Hexamethylenediamine is reacting with adipic acid in the presence of water, there is a formation of nylon\[ - 6,6\]. The adipic acid is a diacid and Hexamethylenediamine is a diamine. And it is a condensation polymer which is obtained by the joining of monomer units by eliminating water molecules. The chemical reaction can be written as,

All the nylons have different characters and it is a family of polymers. Therefore two monomers used to make nylon \[ - 6,6\] are adipic acid and Hexamethylenediamine. Each monomer contains six carbon atoms. The melting temperature of nylon\[ - 6,6\]is very high.

Note:
We need to know that the nylon \[ - 6,6\] is prepared by using diacid and diamines and it is adipic acid and Hexamethylenediamine. The nylon \[ - 6,6\] contains a long polymer chain. And this is classified as synthetic polymer. The nylon \[ - 6,6\] is mainly used to make sheets, and in textile industries, and make parachutes etc. And these are waterproof materials. Hence, it is also used to make swimming suits.
