Question:
Which of the following is an example of copolymer?
Which of the following is an example of copolymer?
Show Hint
Any polymer with multiple parts in its common name (like Buna-S, Buna-N, or Nylon-6,6) is a strong indicator that it is built from two separate monomers working together as a copolymer.
Updated On: Jun 18, 2026
- Polyvinyl chloride
- Nylon-6
- Buna-S
- Polyethylene

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
The question asks to identify a copolymer among the given common polymers. A copolymer is a polymer derived from more than one species of monomer.
Step 2: Key Formula or Approach:
Homopolymers: Polymers synthesized from only a single type of monomer unit.
Copolymers: Polymers synthesized from two or different types of monomer units.
Step 3: Detailed Explanation:
Let's analyze the composition of each option:
Polyvinyl chloride (PVC): Made exclusively from a single monomer, vinyl chloride. (Homopolymer)
Nylon-6: Produced by the self-condensation of a single monomer, caprolactam. (Homopolymer)
Polyethylene: Synthesized purely from ethylene monomers. (Homopolymer)
Buna-S: This is a synthetic rubber formed by the addition copolymerization of two distinct monomeric components: 1,3-butadiene and styrene. Because it links two different chemical building blocks together, it is classified as a copolymer.
Step 4: Final Answer:
The example of a copolymer is Buna-S, which matches option (C).
