Why does the repeating unit of an addition polymer contain the same atoms as its monomer?
Because the monomer contains a carbon to carbon double bond
Because all of the monomer molecules used are the same as each other
Because the polymer chain formed is far longer than the monomer
Because no other molecule is produced in the polymerisation reaction
