Melting point differences of 5–10 °C were found between these polyketones and their reported congeners from ethylene/CO copolymerizations with comparable CO contents, which were related to additional methyl branching occurring in insertion copolymerization. Consequently, ADMET-derived polyketones can act as defect-free model polyketones. Comparison with polymers containing the same degrees of other carbonyl functionalities (esters, carbonates) shows that the partial compensation of the disturbance of polyethylene crystallization goes along with the groups’ polarity.</dcterms:abstract> <dc:contributor>Ortmann, Patrick</dc:contributor> <dc:contributor>Wimmer, Florian P.</dc:contributor> <dc:creator>Mecking, Stefan</dc:creator> <dcterms:title>Long-Spaced Polyketones from ADMET Copolymerizations as Ideal Models for Ethylene/CO Copolymers</dcterms:title> <dc:creator>Wimmer, Florian P.</dc:creator> <dc:creator>Ortmann, Patrick</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-07-14T11:23:01Z</dc:date> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/31418"/> <dcterms:issued>2015</dcterms:issued> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-07-14T11:23:01Z</dcterms:available> <dc:contributor>Mecking, Stefan</dc:contributor> </rdf:Description> </rdf:RDF>
