Polymers
9.0 Nylon-66
9.0 Nylon-66
Polymer which has polyamide linkage ($–CO – NH –$). Therefore these polymers are known as nylons. A nylon$-66$ has hexamethylenediamine and adipic acid as its monomer unit.
It is used for making bristles for brushes, in textiles in making sheets. It is blended with wool to make socks and sweaters, cords and climbing ropes.
$1.$ 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.
$2.$ Nylon$-6, 10$: A polymer of hexamethylene diamine (six carbon atoms) and sebacic acid (ten carbon atoms).
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.
