Bottlebrush polymers can form additive\u2010free PSAs due to their architecture, but most are crosslinked materials that include all\u2010carbon backbones, have thermally unstable disulfide bonds, or do not reach the high molar masses needed for bottlebrush PSAs. Here, we applied the alternating free\u2010radical copolymerization of sulfur dioxide (SO\n                    <jats:sub>2<\/jats:sub>\n                    ) and norbornene\u2010based macromonomers in a grafting\u2010through approach to make bottlebrush polymers with number\u2010average molar masses exceeding 1100\u00a0kg\/mol and backbone degrees of polymerization exceeding 900. These first examples of poly(olefin sulfone) bottlebrush polymers incorporated polyacrylate, polymethacrylate, polystyrene, and poly(lactic acid) side chains, all attached to a poly(norbornene\u2010\n                    <jats:italic>alt<\/jats:italic>\n                    \u2010SO\n                    <jats:sub>2<\/jats:sub>\n                    ) backbone. Under mild alkaline conditions, these very high molecular weight bottlebrush polymers degraded considerably within 10\u00a0min and completely within 4\u00a0h. Finally, a bottlebrush polymer synthesized using this approach behaved as a PSA with a peel strength of \u223c1200\u00a0N\/m, substantially higher than non\u2010degradable PSAs in commercial tapes. In sum, this work offers a versatile approach to synthesize triggerable and degradable bottlebrush polymer adhesives enabling end\u2010of\u2010life disposal following their intended applications.\n
