A group in Kyoto University has developed a synthetic method for polymers containing periodically introduced ketone carbonyl groups through sequence-controlled radical copolymerization and post-polymerization modification. The resulting polymers were thermally stable and degradable by ultraviolet (UV) light.

The authors expect that the ketone skeleton can be used as a motif for polymer degradation, and this molecular design may lead to the development of a new type of polymer material that is stable and durable when in use, and can be decomposed by light when discarded.
