Step 1: Understanding Polymer Types
- Nylon 6 is formed by polymerization of caprolactam, making it a homopolymer.
- It is widely used as a fibre in textiles.
Step 2: Checking Other Options
- Polystyrene is a homopolymer, not a copolymer.
- Bakelite is a condensation polymer, not an addition polymer.
- Buna-N is a copolymer of butadiene and acrylonitrile, not a homopolymer.
Thus, the correct answer is Nylon 6 – Homopolymer – Fibre.
