Condensation polymerisation of caprolactam is carried out in the reactor maintained at a temperature of __________ °C for producing nylon-6?
Correct answer: B. 250-280
- A. -20 to 25
- B. 250-280
- C. 100 to 150
- D. 50 to 75
Explanation
Caprolactam is polymerized industrially at about 250 to 280°C to form nylon-6. Although this process is often described as hydrolytic ring-opening polymerization rather than a strict condensation reaction, the stated operating range is correct.
