The name of the product is:
Think it through first, then pick an option.
- a PVC
- b polypropylene
- c polythene
- d nylon
Answer and explanation
Correct answer: a PVC
Vinyl chloride with organic peroxide at high pressure and temperature gives polyvinyl chloride (PVC).
Why the other options are wrong
- b polypropylene: Polypropylene comes from propene over TiCl₄; this monomer carries Cl, so it is PVC.
- c polythene: Polythene's monomer is CH₂=CH₂, with no Cl; the product is PVC.
- d nylon: Nylon is a condensation polymer of two monomers; this is addition of one monomer, giving PVC.
