The resulting polyether polyols exhibit linear and branched architectures (degrees of branching, DB = 0.27), high catalytic activities with turnover frequencies up to 461 min\u22121, narrow dispersities (1.15\u20131.25), and low levels of unsaturation (0.004 meq g\u22121). The DMC catalysts also enable the efficient synthesis of poly(propylene carbonate) polyol with carbonate contents up to 40% and yields reaching 63%. Additionally, branched poly(ether carbonate) polyols with tunable DB values (0.14\u20130.21), yields up to 70%, and carbonate contents up to 33% are synthesized via CO2 fixation to glycidol. The synthesized polyols hold strong potential for industrial applications in polyurethanes and other advanced materials, offering versatile performance for use in coatings, adhesives, sealants, and elastomers. Overall, this study highlights the effectiveness of DMC catalysts in producing high-performance polyols, contributing to the development of sustainable materials with precise architectural control.<\/jats:p>","DOI":"10.3390\/polym17182458","type":"journal-article","created":{"date-parts":[[2025,9,11]],"date-time":"2025-09-11T10:50:04Z","timestamp":1757587804000},"page":"2458","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Synthesis of Linear and Branched Polycarbonate Polyols via Double Metal Cyanide-Catalyzed Ring-Opening (Co)polymerization of Epoxides"],"prefix":"10.3390","volume":"17","author":[{"given":"Won Seok","family":"Jae","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, Pusan National University, Busandaehag-ro 63-2, Geumjeong-gu, Busan 46241, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ha-Kyung","family":"Choi","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Pusan National University, Busandaehag-ro 63-2, Geumjeong-gu, Busan 46241, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Han Su","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Pusan National University, Busandaehag-ro 63-2, Geumjeong-gu, Busan 46241, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0151-2126","authenticated-orcid":false,"given":"Chinh Hoang","family":"Tran","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Pusan National University, Busandaehag-ro 63-2, Geumjeong-gu, Busan 46241, Republic of Korea"},{"name":"Institute of Advanced Technology, Vietnam Academy of Science and Technology, TL29 Street, An Phu Dong, Ho Chi Minh 70000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chi Le Hoang","family":"Tran","sequence":"additional","affiliation":[{"name":"FPT University, FPT Polytechnic, Nguyen Van Cu Street, An Binh, Can Tho 90000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khoa Anh","family":"Trinh","sequence":"additional","affiliation":[{"name":"FPT University, FPT Polytechnic, Nguyen Van Cu Street, An Binh, Can Tho 90000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8047-7543","authenticated-orcid":false,"given":"Il","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Pusan National University, Busandaehag-ro 63-2, Geumjeong-gu, Busan 46241, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1038\/239023a0","article-title":"Man-made Carbon Dioxide and the \u201cGreenhouse\u201d Effect","volume":"239","author":"Sawyer","year":"1972","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/j.cattod.2006.02.024","article-title":"Aspects of carbon dioxide utilization","volume":"115","author":"Omae","year":"2006","journal-title":"Catal.
