As hexene is increasingly consumed, this cation decays, mainly back to [rac-Me(2)Si(ind)(2)Zr(mu-Me)(2)AlMe(2)](+) and, in part, to some species containing a Zr-bound allylic chain end.</dcterms:abstract> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:12:43Z</dc:date> <dc:format>application/pdf</dc:format> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9556"/> <dc:rights>deposit-license</dc:rights> <dc:contributor>Brintzinger, Hans H.</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Journal of the American Chemical Society : JACS ; 132 (2010), 2. - S. 452-453</dcterms:bibliographicCitation> <dcterms:issued>2010</dcterms:issued> <dc:creator>Brintzinger, Hans H.</dc:creator> <dcterms:title>Reactive Intermediates Formed During Olefin Polymerization by Methylalumoxane-Activated ansa-Zirconocene Catalysts : Identification of a Chain-Carrying Intermediate by NMR Methods</dcterms:title> <dc:contributor>Babushkin, Dmitrii E.</dc:contributor> <dc:language>eng</dc:language> <dc:creator>Babushkin, Dmitrii E.</dc:creator> </rdf:Description> </rdf:RDF>
