Typical solvent polymerisation reaction conditions for the production of high density polythene by Zeigler process is__________________?
Correct answer: C. 7 kgf/cm2 and 70 °C
- A. 7 kgf/cm2 and 700°C
- B. 1000 kgf/cm2 and 100°C
- C. 7 kgf/cm2 and 70 °C
- D. 1 kgf/cm2 (gage) and 70°C
Explanation
Low-pressure Ziegler polymerisation commonly operates near 7 kgf/cm² and 70 °C in a hydrocarbon solvent. The 1000 kgf/cm² condition belongs to high-pressure polyethylene production, while 700 °C is far too high for this process.
