Polyvinyl chloride (PVC) ____________________?
Correct answer: B. Uses either emulsion or suspension polymerisation methods
- A. Is produced by Polycondensation reaction
- B. Uses either emulsion or suspension polymerisation methods
- C. Can be made thermosetting by adding a plasticiser
- D. Softening temperature is 200°C
Explanation
PVC is an addition polymer commonly manufactured by suspension or emulsion polymerisation. Plasticisers make PVC flexible, not thermosetting, and its softening temperature is well below 200°C.
