Low pressure Zeigler process of polythene manufacture____________________?
Correct answer: B. Achieves an yield of 95-98% based on ethylene
- A. Employs a pressure of 30 kgf/cm2
- B. Achieves an yield of 95-98% based on ethylene
- C. Produces very low density polythene
- D. Does not use any catalyst for polymerisation
Explanation
The low-pressure Ziegler process uses a catalyst and converts ethylene with a high yield, commonly about 95 to 98 percent. It produces high-density, not very-low-density, polyethylene, so option c is incorrect.
