Question

Name the process by which Nylon-6,6 is obtained.

Answer 1

Understanding polymerization:

• Polymerization is a chemical reaction in which many monomeric units that (may be the same or different) bond chemically to form a high molecular weight polymer.
• Condensation polymerization is a chemical reaction in which monomeric units are chemically bonded by the removal of water.
• The formation of Nylon-6,6 is an example of condensation polymerization.
• In this reaction, Hexamethylenediamine reacts with adipic acid to give Nylon-6,6.
• $\mathrm{n}\underset{\mathrm{Adipic}\mathrm{Acid}}{\mathrm{HOOC}-{\left({\mathrm{CH}}_2\right)}_4-\mathrm{COOH}}+\mathrm{n}\underset{\mathrm{Hexamethylene}\mathrm{diamine}}{{\mathrm{H}}_2\mathrm{N}-{\left({\mathrm{CH}}_2\right)}_6-{\mathrm{NH}}_2}\to \underset{\mathrm{Nylon}-6,6}{[-\mathrm{CO}-{\left({\mathrm{CH}}_2\right)}_4-\mathrm{CO}-\mathrm{NH}-{\left({\mathrm{CH}}_2\right)}_6-\mathrm{NH}-]\mathrm{n}}+\underset{\mathrm{Water}}{(2\mathrm{n}-1){\mathrm{H}}_2\mathrm{O}}$
