Chain-growth polymers are synthesized by radical polymerization of alkenes. The mechanism for a radical polymerization of alkenes is given below. Polystyrene, also shown below, is polymeric chain made up of thousands of monomeric groups with a total molecular weight of the polymer between 100,000 and 400,000 g/mol. What is the monomer used to synthesize polystyrene?

Allylic halides can be synthesized under radical conditions (hv or peroxides) where the concentration of the molecular halogen is low.
