(a) Illustration of possible termination products for free radical polymerization of polystyrene. (b) Polystyrene ring polymer synthesized from azide–alkyne click chemistry. Since the rings and cycles within the repeating units are independent of the macrocycle (that lead to the formation of the ring polymer), the ring closure integer identifier within the stochastic object is independent of the identifiers outside of the object even if the numbers were the same. (c) Ring polymer synthesized from ring expansion metathesis polymerization (REMP).
