What is the monomer used to make polypropene?

Explanation:
Propene is the monomer used to make polypropene. In addition polymerization, the C=C double bond in propene (CH2=CH-CH3) opens and many propene molecules join end-to-end to form long chains. The repeating unit in the polymer is -CH2-CH(CH3)-, reflecting the methyl group from each propene unit along the backbone. This gives polypropylene its characteristic structure. If you started with ethene, you’d get polyethylene; with butene you’d get polybutene; and methene isn’t a practical monomer. So propene is the correct monomer.
