Temperature maintained in the emulsion polymerisation reactor for PVC manufacture is about ______________ ° C?
Correct answer: B. 50
- A. -20
- B. 50
- C. 250
- D. 500
Explanation
PVC emulsion polymerisation is commonly conducted near 50°C, where the initiator and emulsion system provide a practical polymerisation rate. The other temperatures are either below normal operation or far too high for this process.
