What can alkenes be used to make?
Polymers such as polyethene and ploypropene
What happens in addition polymerisation reactions?
Many small molecules (monomers) join together to make very large molecules called polymers
Are any other products formed in addition polymerisation?
No - each repeating unit in the polymer has the same atoms as the monomer
What do monomers contain?
Double bonds which break during the reaction
