Transforming end\u2010of\u2010life PET into (bio)degradable polyester offers a novel approach to managing its waste. In this study, we introduce a simple process capable of converting waste PET into degradable polyester, polyethylene terephthalate\u2010polyethylene\u20101,4\u2010cyclohexanedicarboxylate (PET\u2010PECHD), by partly hydrogenating the aromatic rings (\n                    <jats:bold>x<\/jats:bold>\n                    ) into aliphatic ones (\n                    <jats:bold>y<\/jats:bold>\n                    ). The polyesters with variable\n                    <jats:bold>x<\/jats:bold>\n                    \/\n                    <jats:bold>y<\/jats:bold>\n                    compositions ranging from 100\/0 to 0\/100 can be achieved, and the molecular weight (Mw) can be maintained when\n                    <jats:bold>x<\/jats:bold>\n                    \/\n                    <jats:bold>y<\/jats:bold>\n                    &gt;87\/13 due to the nonobvious depolymerization. Pronounced depolymerization would occur with deeper hydrogenation, which generates a blend of PET\u2010PECHD and polyethylene\u20101,4\u2010cyclohexanedicarboxylate (PECHD) with lower Mw, and finally a single\u2010type polymer PECHD. The PET\u2010PECHD demonstrates comparable thermal stability and mechanical strength compared to PET, along with superior extensibility, barrier properties, and (bio)degradability in acidic, alkaline solutions, and moist soil. This research highlights the potential for cost\u2010effective, large\u2010scale production of degradable polyester from real\u2010life plastic waste.\n                  <\/jats:p>","DOI":"10.1002\/anie.202418157","type":"journal-article","created":{"date-parts":[[2024,11,3]],"date-time":"2024-11-03T23:44:55Z","timestamp":1730677495000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Hydrogenating Polyethylene Terephthalate into Degradable Polyesters"],"prefix":"10.1002","volume":"64","author":[{"given":"Zhenbo","family":"Guo","sequence":"first","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences New Cornerstone Science Laboratory College of Chemistry and Molecular Engineering Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoran","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences Key Laboratory of Polymer Chemistry and Physics of Ministry of Education Center for Soft Matter Science and Engineering College of Chemistry and Molecular Engineering Peking University  Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyu","family":"Chen","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences New Cornerstone Science Laboratory College of Chemistry and Molecular Engineering Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meiqi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences New Cornerstone Science Laboratory College of Chemistry and Molecular Engineering Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyan","family":"Tang","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences Key Laboratory of Polymer Chemistry and Physics of Ministry of Education Center for Soft Matter Science and Engineering College of Chemistry and Molecular Engineering Peking University  Beijing 100871 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences New Cornerstone Science Laboratory College of Chemistry and Molecular Engineering Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3341-2998","authenticated-orcid":false,"given":"Ding","family":"Ma","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Molecular Sciences New Cornerstone Science Laboratory College of Chemistry and Molecular Engineering Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,11,21]]},"reference":[{"key":"e_1_2_7_1_1","unstructured":"PlasticsEurope.
