Vulcanization involves the removal of
a monomer
the single bond
the double bond
a polymer
Explication
Vulcanization can cause isomerization of a double bond. This isomerization is a type of stereoisomerism, which is a change in the relative positions of atoms in a molecule. Vulcanization is a process that hardens rubber by forming cross-links between polymer chains.
