As discussed in Chapters 25 and 26, a polymer is a very large molecule that contains many repeating units called monomers. The reaction here shows, for example, how styrene reacts to form polystyrene. The reaction is initiated by the electrophilic addition of H+ from an acid like sulfuric acid, which generates an initial carbocation. Afterward, that carbocation behaves as an electrophile in the presence of another molecule of styrene, resulting in yet another carbocation. This reaction can repeat many thousands of times to build up the polymer. With this in mind, draw the detailed mechanism that illustrates the initiation of the polymerization reaction and the addition of the first two monomers, as shown at the right.
