Question

Give equation of chemical reaction for preparation of nylon 6. Write answer in brief.

Answer 1

Nylon is a synthetic polymer .

• It is prepared by condensation polymerization.

• In these polymerization reactions, small molecules like water , hydrogen chloride are eliminated.

Formation of NYLON -6,6:

It is prepared by the condensation polymerization of hexamethylenediamine  with adipic acid under high pressure and at high temperature.

hexamethylenediamine             adipic acid
