The reaction was found to be applicable to polymer-polymer coupling, as judged by SEC, DOSY NMR, and LCxSEC analyses, giving diblock copolymers by merely mixing the constituent homopolymers together under ambient conditions, using no catalyst, additive, or external stimulus.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Hansell</LastName><ForeName>Claire F</ForeName><Initials>CF</Initials><AffiliationInfo><Affiliation>Department of Chemistry, University of Warwick, Coventry, UK.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Espeel</LastName><ForeName>Pieter</ForeName><Initials>P</Initials></Author><Author ValidYN="Y"><LastName>Stamenovi&#x107;</LastName><ForeName>Milan M</ForeName><Initials>MM</Initials></Author><Author ValidYN="Y"><LastName>Barker</LastName><ForeName>Ian A</ForeName><Initials>IA</Initials></Author><Author ValidYN="Y"><LastName>Dove</LastName><ForeName>Andrew P</ForeName><Initials>AP</Initials></Author><Author ValidYN="Y"><LastName>Du Prez</LastName><ForeName>Filip E</ForeName><Initials>FE</Initials></Author><Author ValidYN="Y"><LastName>O'Reilly</LastName><ForeName>Rachel K</ForeName><Initials>RK</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2011</Year><Month>08</Month><Day>11</Day></ArticleDate></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>J Am Chem Soc</MedlineTA><NlmUniqueID>7503056</NlmUniqueID><ISSNLinking>0002-7863</ISSNLinking></MedlineJournalInfo></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2011</Year><Month>8</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2011</Year><Month>8</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2011</Year><Month>8</Month><Day>9</Day><Hour>6</Hour><Minute>1</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">21819063</ArticleId><ArticleId IdType="doi">10.1021/ja203957h</ArticleId></ArticleIdList></PubmedData></PubmedArticle></PubmedArticleSet>
