Question

Give the preparation properties and use of nylon 6 6 ?

Answer 1

The physical properties of nylon 6,6 is that :

1. Nylon 6,6 has a repeat unit with molecular weight of  is 226.32 g/mol and crystalline density of 1.24 g/(cm)^3 .

2.Nylon 6,6 has long molecular chains resulting in more  hydrogen bonds , creating chemical springs and making it very resilient .

The applications of Nylon 6,6 is : 
 > Nylon 6,6 is waterproof in nature so it is also used to make swimwear.

 > Nylon 6,6 having a high melting point make it more resistant to heat and friction so it is suitable to be used in  in airports , offices and other places which are more liable to wear 

Answer 2

Equivalent amounts of hexamethylenediamine and adipic acid are combined with water in a reactor. This is crystallized to make nylon salt, an ammonium/carboxylate mixture. The nylon salt goes into a reaction vessel where polymerization process takes place either in batches or continuously.

Used in rope making and parachutes.
