To date, well-defined narrow dispersity bottlebrush polymers remain a highly heterogeneous soft material because they are prepared through polymerizing disperse macromonomer building blocks. Here we describe the synthesis of topologically precise and truly discrete bottlebrush polymers (<i>D</i> = 1.0) using discrete macromonomers. Owing to the discrete nature of the side chains, the resulting bottlebrush polymers can be designed with accurate and uniform multi-block topology. Such topology can be harnessed to control their thermomechanical properties without changing their chemical make-up. Our results highlight the importance of precision building blocks in advancing structure-property relationship studies and the development of precision polymer platforms.
