Herein, we first reported a recyclable polycarbonate based on structurally rigid and acid-sensitive spirocyclic acetal units, which exhibited excellent mechanical properties and transparency. The use of biosourced vanillin as a multifunctional building block achieved a circular life cycle for the chemical materials. The copolycarbonates exhibited a high glass transition temperature (\u2265143 \u00b0C) and tensile strength (\u226557 MPa), comparable to those of BPA-PC. Under mild acidic conditions (pH \u2248 6), the acetal linkages were selectively cleaved while carbonate groups remained intact, yielding telechelic polymers with aldehyde termini. These degradation products were efficiently reconverted to the original copolycarbonates, closing the loop for chemical recycling. This strategy offered a sustainable pathway toward a circular polycarbonate economy.<\/jats:p>","DOI":"10.1021\/acs.biomac.6c00488","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T05:55:12Z","timestamp":1784094912000},"page":"5276-5286","source":"Crossref","is-referenced-by-count":0,"title":["Chemical Recycling\nfor Polycarbonates Mediated by\nSpirocyclic Acetal Trigger"],"prefix":"10.1021","volume":"27","author":[{"given":"Xiaolong","family":"Wang","sequence":"first","affiliation":[{"name":"Tiangong University , , ,","place":["Tianjin, PR China, 300387"]},{"name":"Cangzhou Insititute of Tiangong University , ,","place":["Cangzhou, PR China, 061000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shikai","family":"Zhou","sequence":"additional","affiliation":[{"name":"Tiangong University , , ,","place":["Tianjin, PR China, 300387"]},{"name":"Cangzhou Insititute of Tiangong University , ,","place":["Cangzhou, PR China, 061000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuedong","family":"Lv","sequence":"additional","affiliation":[{"name":"Tiangong University , , ,","place":["Tianjin, PR China, 300387"]},{"name":"Cangzhou Insititute of Tiangong University , ,","place":["Cangzhou, PR China, 061000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"Tiangong University , , ,","place":["Tianjin, PR China, 300387"]},{"name":"Tiangong University , , ,","place":["Tianjin, China, 300387"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6538-4805","authenticated-orcid":true,"given":"Liuchun","family":"Zheng","sequence":"additional","affiliation":[{"name":"Tiangong University , , ,","place":["Tianjin, PR China, 300387"]},{"name":"Cangzhou Insititute of Tiangong University , ,","place":["Cangzhou, PR China, 061000"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"issue":"7","key":"2026081008072525900_cit1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.1700782","article-title":"Production, use, and fate of all\nplastics ever made","volume":"3","author":"Geyer","year":"2017","journal-title":"Sci.
