What is the structure of nylon-6, made by alkaline polymerisation of caprolactum?

Explanation

The configuration of these carbons which are unchanged in the reactions, must be identical in order to get the same osazone.
(a) Nylon-6 : Another polymer of this class is nylon-6. It is a monomer of caprolactum which is obtained from cyclohexane.

It used for making tyre cords, fabrics and ropes.
(b) Nylon-6,10 : A polymer of hexamethylene diamine (six carbon atoms) and sedacic acid (ten carbon atoms).
`{:(nNH_2 - (CH_2)_6- NH_2+nCOOH- (CH_2)_8 -COOH overset(-2nH_2O)(to) (-CO-(CH_2)_8-NH-(CH_2)_6 -NH -CO-(CH_2)_8-CO-)_n),(" hexamethylene diamine sebacic acid Nylon-6,10 "):}`
These polymers are formed by the condensation of two or more monomers with the elimination of simple molecules like `H_2O,NH_3,ROH` etc.
