Question

Which of the following is a copolymer?

• A. Polyvinyl chloride (PVC)
• B. Nylon - 6,6
• C. Natural rubber
• D. Polyethylene

Answer 1

The correct option is B

Nylon - 6,6

The explanation for the correct option:

(B) Nylon - 6,6

1. A copolymer is one that is made up of combining two or more monomer units.
2. A nylon-6,6 is prepared by polymerizing Adipic acid and hexamethylene diamine.
3. As two different monomers are involved, nylon-6,6 is a copolymer.

The explanation for the incorrect options:

(A) Polyvinyl chloride is prepared by combining only vinyl chloride units. Thus, it has only one monomer.

(C) Natural rubber is a polymer of isoprene units, Thus, it has only one monomer.

(D) Polyethylene is a polymer of polyethylene units, Thus, it has only one monomer.

Hence, the correct option is (B), Nylon - 6,6
