Polyvinyl chloride (PVC) ____________________?
Correct answer: D. Uses either emulsion or suspension polymerisation methods
- A. Is produced by Polycondensation reaction
- B. Softening temperature is 200°C
- C. Can be made thermosetting by adding a plasticiser
- D. Uses either emulsion or suspension polymerisation methods
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.
