Question

What does the part ‘6, 6’ mean in the name nylon-6, 6?

Answer 1

Answer:

Adipic acid and hexamethylene diamine are used to prepare nylon-6,6. Since hexamethylene diamine and adipic acid both have six carbon atoms, the nylon they form is called nylon 6-6, or polyamide 6-6.

Answer 2

Answer:

Nylon ‘6,6’ implies that it is a condensation polymer of two types of monomer molecules each containing six carbon atoms i.e. adipic acid (HOOC (CH2)4 COOH) and hexamethylenediamine (H2N CH2 CH2 CH2 CH2 CH2 CH2 NH2)
