A strategy to control sequence of vinyl polymers

“Sequence” or the order of repeating units can be regarded as an essential structural factor for polymers, because functions in natural polymers such as DNA and proteins are totally determined by the sequence. However, there are little methodologies to control sequence for synthetic counterparts. In this research, we propose a strategy to control sequence for vinyl polymers via iterative cyclization, which is realized by design of two kinds of “cleavable but renewable bonds” in molecules for living radical polymerization. Sequence control is expected to contribute to development of functional materials.
