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 for nylon 6, 10:-
- 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.
