Question

What are the monomeric
repeating units of Nylon−$6$ and Nylon−$6$,$6$?

Answer 1

$\text{Monomeric repeating units of Nylon−}6$

Nylon-$6$ is obtained by heating caprolactam with water at a high temperature.

It has $-CO-(C{H}_2{)}_5-NH-$ as monomeric repeating unit which is derived from caprolactam.

Polymerisation reaction of nylon-$6$ is shown below-


$\text{Monomeric repeating units of Nylon−}6\text{,}6$

The monomer repeating unit of Nylon-$6$,$6$ is derived from $2$ monomers, hexamethylenediamine and adipic acid and has the following structure
