90% of the caprolactam is converted to nylon-6 on its condensation polymerisation in the reactor maintained at a temperature of _____________ °C?
Correct answer: C. 250-280
- A. -5
- B. 10-30
- C. 250-280
- D. 500-600
Explanation
Caprolactam ring-opening polymerisation to nylon-6 is carried out at about 250 to 280°C. The other temperatures are either far too low for the reaction or impractically high for the polymer.
