Example of copolymers is _____________?
Correct answer: D. nylon 6-6
- A. Polyethylene
- B. PVC
- C. Orlon
- D. nylon 6-6
Explanation
Nylon 6,6 is a copolymer because it is formed from two different monomers, hexamethylene diamine and adipic acid. Polyethylene, PVC and Orlon are generally treated as homopolymers because each is formed from one principal monomer. The likely wrong choice is Orlon because it is synthetic, but being synthetic does not by itself make a polymer a copolymer.

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.
