The catalytic activity of benzimidazolium acetates to promote transesterification reactions using molecular compounds is first demonstrated. Subsequently, polymer networks were synthesized via thermally\u2010initiated free\u2010radical copolymerization of 4\u2010vinylbenzyl\u2010ethyl\u2010benzimidazolium acetate in combination with commercial mono\u2010 and bis\u2010acrylates. Loading as low as 5 mol% was sufficient to activate transesterification exchange reactions within the polymer matrix, enabling reprocessability by compression molding. Photo\u2010rheological properties of this vitrimer formulation were investigated, demonstrating its compatibility with Digital Light Processing (DLP) 3D printing toward the fabrication of high\u2010resolution objects showing good surface fidelity and well\u2010defined features. Notably, the covalent incorporation of benzimidazolium acetate salts does not interfere with the photopolymerization process. In addition, their catalytic activity toward transesterification reactions offers attractive end\u2010of\u2010life scenarios for the printed materials.<\/jats:p>","DOI":"10.1002\/marc.70388","type":"journal-article","created":{"date-parts":[[2026,8,1]],"date-time":"2026-08-01T13:05:28Z","timestamp":1785589528000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Covalent Integration of Benzimidazolium Acetate Units in Light\u2010Induced 3D\u2010Printable Acrylate\u2010Based Vitrimers"],"prefix":"10.1002","author":[{"given":"Karine","family":"Abou Ezze","sequence":"first","affiliation":[{"name":"Laboratoire De Chimie des Polym\u00e8res Organiques (LCPO) UMR 5629 Universit\u00e9 De Bordeaux CNRS Bordeaux INP  Pessac France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-1355-0510","authenticated-orcid":false,"given":"Cl\u00e9ment","family":"Soler","sequence":"additional","affiliation":[{"name":"Laboratoire De Chimie des Polym\u00e8res Organiques (LCPO) UMR 5629 Universit\u00e9 De Bordeaux CNRS Bordeaux INP  Pessac France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4960-836X","authenticated-orcid":false,"given":"C\u00e9dric","family":"Le Coz","sequence":"additional","affiliation":[{"name":"Laboratoire De Chimie des Polym\u00e8res Organiques (LCPO) UMR 5629 Universit\u00e9 De Bordeaux CNRS Bordeaux INP  Pessac France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8539-4963","authenticated-orcid":false,"given":"Daniel","family":"Taton","sequence":"additional","affiliation":[{"name":"Laboratoire De Chimie des Polym\u00e8res Organiques (LCPO) UMR 5629 Universit\u00e9 De Bordeaux CNRS Bordeaux INP  Pessac France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6218-3418","authenticated-orcid":false,"given":"Thomas","family":"Vidil","sequence":"additional","affiliation":[{"name":"Laboratoire De Chimie des Polym\u00e8res Organiques (LCPO) UMR 5629 Universit\u00e9 De Bordeaux CNRS Bordeaux INP  Pessac France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5977-2564","authenticated-orcid":false,"given":"Audrey","family":"Llevot","sequence":"additional","affiliation":[{"name":"Laboratoire De Chimie des Polym\u00e8res Organiques (LCPO) UMR 5629 Universit\u00e9 De Bordeaux CNRS Bordeaux INP  Pessac France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,1]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202108932"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/app.52816"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/app.51977"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0MA00873G"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202104798"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpcb.1c03511"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mattod.2021.01.009"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.2c00231"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00366\u2010015\u20100407\u20100"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/mz4006556"},{"key":"e_1_2_8_12_1","first-page":"169","volume-title":"NMR\u20103D Analysis\u2010Photopolymerization","author":"Sun H.
