Which polymer has chloroethene as its monomer?

Explanation:
Chloroethene, also known as vinyl chloride, has the structure CH2=CHCl. When many of these monomer units join by addition polymerization, the double bonds open and the repeating unit becomes -CH2-CHCl-, giving poly(chloroethene), which is the polymer commonly called PVC. This is the polymer formed from chloroethene, hence the correct choice. Other polymers come from different monomers: polythene from ethene, polypropene from propene, and polystyrene from styrene, so they aren’t made from chloroethene.
