Nylon is obtained by heating___________________?
Correct answer: D. Adipic acid with hexamethylene diamine
- A. Acrylic acid
- B. Epichlorohydrin
- C. Vinyl chloride
- D. Adipic acid with hexamethylene diamine
Explanation
Nylon-6,6 is made by condensation polymerization of adipic acid with hexamethylene diamine, producing polyamide chains and water. A student may choose vinyl chloride because it is a monomer, but vinyl chloride forms PVC, not nylon.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
