Lewis acid\/base pairs (LPs) exhibit high activity (EO conversion up to &gt;99%, 8\u00a0h) in catalyzing the copolymerization under low Lewis pair\/monomer ratio of 1:1500. Oxygen\u2013sulfur exchange reaction (O\u2013S ER) during the copolymerization of CS<jats:sub>2<\/jats:sub> and EO, the generation and mutual copolymerization with COS, CO<jats:sub>2<\/jats:sub>, and episulfide, is harnessed to introduce crystallizable segments [\uf8ffSC(\uf8feO)O\uf8ff and \uf8ffSC(\uf8feS)S\uf8ff] in the copolymer. The type of Lewis base is found to have a great impact on the chain microstructure and the crystalline properties. The formed copolymers with melting point from 117.7 to 245.3\u00a0\u00b0C are obtained. The maximum crystallinity is estimated to be 78% based on the powder wide\u2010angle X\u2010ray diffraction pattern. This work provides a general method to prepare semicrystalline sulfur\u2010containing polymers.<\/jats:p>","DOI":"10.1002\/marc.202000472","type":"journal-article","created":{"date-parts":[[2020,11,18]],"date-time":"2020-11-18T10:38:13Z","timestamp":1605695893000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Enabling Oxygen\u2013Sulfur Exchange Reaction to Produce Semicrystalline Copolymers from Carbon Disulfide and Ethylene Oxide"],"prefix":"10.1002","volume":"42","author":[{"given":"Jia\u2010Liang","family":"Yang","sequence":"first","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310027 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Wang","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310027 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao\u2010Han","family":"Cao","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310027 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheng\u2010Jian","family":"Zhang","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310027 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zheng","family":"Chen","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310027 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6543-0042","authenticated-orcid":false,"given":"Xing\u2010Hong","family":"Zhang","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310027 China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,11,18]]},"reference":[{"key":"e_1_2_4_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chempr.2018.10.011"},{"key":"e_1_2_4_2_1","unstructured":"Ellen MacArthur Foundation"},{"key":"e_1_2_4_3_1","unstructured":"Polyethylene: Analysis of PE production in China"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1125268"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7CS00149E"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.progpolymsci.2008.10.002"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7GC02560B"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature21001"},{"key":"e_1_2_4_9_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aar5498"},{"key":"e_1_2_4_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.polymer.2015.11.011"},{"key":"e_1_2_4_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2018.06.004"},{"key":"e_1_2_4_12_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8PY00119G"},{"key":"e_1_2_4_13_1","unstructured":"S.Inoue H.Koinuma T.Tsuruta in17th Polymer Symp.
