There has been a growing movement to effectively utilize phenylpropanoids as biomass resources for polymer materials in pursuit of a sustainable society.Isoeugenol, an aromatic biomass resource, is expected to be a sustainable polymer feedstock from the viewpoint of availability and price.On the other hand, due to its -substituted styrene structure, it has poor reactivity in cation/radical polymerization and is difficult to polymerize on its own.In this study, we focused on catalytic 3 + 2 cycloaddition reactions of isoeugenol and utilized it for polymerization.Specifically, we designed a bifunctional monomer consisting of two isoeugenol molecules bonded by silicon to achieve efficient polymerization using catalytic 3 + 2 cycloaddition reactions.Furthermore, the polymer was decomposable under mild conditions, and the decomposition products were suitable for chemical recycling and upcycling.
