The monomer buta-1,3-diene can also take part in addition polymerisation in more than one way. Two polymers that can be formed are known as cis-poly(buta-1,3-diene) and trans-poly(buta-1,3-diene). In these names, cis and trans keep their standard meanings. State the structure of the repeat unit in cis-poly(buta-1,3-diene).
