Nylon-6,6 is the polymer of:
Correct answer: A. Hexamethylene diamine and Adipic acid
- A. Hexamethylene diamine and Adipic acid
- B. Ethylene glycol and Phthalic acid
- C. Ethylene glycol and Adipic acid
- D. Hexamethylene diamine and Phthalic Acid
Explanation
Nylon-6,6 is a polymer formed by the condensation polymerization of hexamethylene diamine and adipic acid. Hexamethylene diamine provides the amine functional group (-NH2), and adipic acid provides the carboxylic acid functional group (-COOH). These functional groups react to form amide bonds (-CONH-) in a condensation reaction, creating the repeating unit of nylon-6,6.

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.
