A potential solution is to design polymers that are robust and stable during normal use but can be degraded on demand and enable new strategies for degradation and recycling. Herein, we present a versatile light\u2010mediated synthetic approach to prepare degradable polymers, including both linear and nonlinear architectures. Our approach involves the controlled radical polymerization via reversible addition\u2010fragmentation chain transfer (RAFT) of various vinyl monomers along with 1,2\u2010dithiolane\u2010based comonomers, which introduce disulfide bonds into the polymer backbone, enabling efficient degradation. Similar to conventional photoiniferter RAFT polymerization, light initiates the copolymerization and simultaneously generates thiyl radicals that react with growing chain radicals to propagate the polymerization. We demonstrate through the use of 1,2\u2010dithiolane\u2010functionalized inimers and selective excitation of CTAs that we can produce nonlinear polymers, including hyperbranched and graft polymers. This mild and versatile approach offers a promising strategy for designing and synthesizing degradable polymers with tailored architectures.<\/jats:p>","DOI":"10.1002\/marc.202600006","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T05:55:46Z","timestamp":1773640546000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Light\u2010Mediated
