-type RAFT step-growth polymerization to yield graft polymer containing a TTC unit in every repeat unit of the backbone. The uniform incorporation of TTC linkages enables efficient main-chain deconstruction under mild conditions, producing well-defined macromonomers with narrow molecular weight distributions. Importantly, the deconstructed products can be efficiently reconstructed into graft polymers via RAFT step-growth polymerization, enabling deconstruction-reconstruction cycles with high yields. This work establishes a simple and effective platform for the circular recycling of graft polymers while preserving precise architectural control, offering new opportunities for sustainable design of advanced macromolecular materials.
