Cyclic polymers, notable for their lack of chain ends, are a rarity in the polymer literature. Even more rare are cyclic polymers prepared from vinyl monomers. This talk will detail recent work synthesizing and characterizing the cyclic topology of vinyl-derived cyclic polymers. This chemistry is driven by a small-molecule macrocycle containing a photoiniferter moiety. Light-driven homolytic cleavage of the photoiniferter group and compatibility with a wide array of commercially-available vinyl monomers enables the preparation of cyclic polymers. Specific focus will be given to techniques used to verify and quantify the cyclic polymer products.
