Preparation of polyamides:-

Polymers having the amide linkage are called as polyamides these are prepared by condensation reaction of the dibasic acids. These polymers are normally called as nylons.

Nylon 6,6 :- It is manufactured by condensation polymerisation of adipic acid and hexamethylenediamine.

Reaction:-


Reaction for nylon 6, 10:-

Uses:-

  • These are used in manufactured of carpets, textile Fibres, bristles and brushes.
  • Being tough nylon is used a substitute for metals in bearings and gears.

When caprolactum is heated with a trace of water, it is hydrolyses to aminocaproic acid (6-aminohexanoic acid) which on continues heating give nylon-6.
