Question

Nylon-6,6 is a:
A. Natural polymer
B. Condensation polymer
C. Addition polymer
D. Substitution polymer

Answer 1

Hint: Nylon – 66 is formed with the help of two monomers, each of which contains six carbon atoms. The monomers are hexamethylenediamine and adipic acid. It is formed by the polycondensation of the two monomers.

Complete Step by Step Solution:
First we know about Nylon - 6,6
Nylon 6, 6 belongs to the family of synthetic polymers which have linear amide linkages which are known as linear polyamides or nylon. It is synthesised or prepared by the condensation of two similar monomers having 6 carbon atoms, hexamethylenediamine, and adipic acid.
Synthesis Of Nylon 6 6

Synthesising or manufacturing the polymer Nylon 6,6 is a step-growth polymerization process that arise through the polycondensation technique, where two monomers hexamethylenediamine $({{H}_{2}}N-{{(C{{H}_{2}})}_{6}}-N{{H}_{2}})$ & adipic acid $(HOOC-{{(C{{H}_{2}})}_{4}}-COOH)$ are condensed to form a polymer called Nylon 6,6. This reaction doesn’t need the catalyst to enhance the rate of the reaction as one of the monomer ie. adipic acid itself acts as a catalyst. Nylon 6,6 is a fibre used in the textile and plastic industries and in daily activities of life.

Note: It is important to note that, cellulose cannot be synthesised by humans because humans take energy from carbohydrates present in food by breaking it into glucose with the help of suitable enzymes but it is very difficult to break cellulose bonding because of the lack of enzyme need to break it.
