However, developing sustainable thermosets with degradability and recyclability faces several principal challenges, including reconciling the desired characteristics during service with the recycling and reprocessing properties required at the end of life, establishing efficient methods for large\u2010scale synthesis, and aligning with current manufacturing process. Here a general strategy is presented for the on\u2010demand degradation and recycling of thermosets under mild conditions utilizing dynamic precursors with dual\u2010factor\u2010controlled reversibility. Specifically, dynamic triazine crosslinkers are introduced through dynamic nucleophilic aromatic substitution (S\n                    <jats:sub>N<\/jats:sub>\n                    Ar) into the precursor polyols used in polyurethane (PU) synthesis. Upon removal of the catalyst and alcohol, the reversibility of S\n                    <jats:sub>N<\/jats:sub>\n                    Ar is deactivated, allowing for the use of standard PU polymerization techniques such as injection molding, casting, and foaming. The resulting cyanurate\u2010crosslinked PUs maintain high stability and diverse mechanical properties of traditional crosslinked PUs, yet offer the advantage of easy on\u2010demand depolymerization for recycling by activating the reversibility of S\n                    <jats:sub>N<\/jats:sub>\n                    Ar under specific but mild conditions\u2014a combination of base, alcohol, and mild heat. It is envisioned that this approach, involving the pre\u2010installation of dual\u2010factor\u2010controlled dynamic crosslinkers, can be broadly applied to current thermosetting plastic manufacturing processes, introducing enhanced\u00a0sustainability.\n                  <\/jats:p>","DOI":"10.1002\/adma.202407854","type":"journal-article","created":{"date-parts":[[2024,9,3]],"date-time":"2024-09-03T08:26:33Z","timestamp":1725351993000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Dual\u2010Factor\u2010Controlled Dynamic Precursors Enable On\u2010Demand Thermoset Degradation and Recycling"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8682-8508","authenticated-orcid":false,"given":"Zepeng","family":"Lei","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Colorado Boulder  Boulder CO 80309 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zirui","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Colorado Boulder  Boulder CO 80309 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huan","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering University of Colorado Denver  Denver CO 80217 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jackson R.","family":"Cahn","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Colorado Boulder  Boulder CO 80309 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4075-247X","authenticated-orcid":false,"given":"Hongxuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Colorado Boulder  Boulder CO 80309 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2565-0005","authenticated-orcid":false,"given":"Shaofeng","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Colorado Boulder  Boulder CO 80309 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinghua","family":"Jin","sequence":"additional","affiliation":[{"name":"RockyTech, Ltd.
