These complexes polymerize ethylene to very small (10−30 nm) semicrystalline particles of high molecular weight (up to Mw 1.6 × 106 g mol−1) polymer with a degree of branching (7−63 branches per 1000 C atoms) and thus crystallinity (≤25−50%) and melt transition temperatures (Tm = 75−129 °C) variable over a large range, depending on the substituents of the N-aryl moiety (2,6-R2C6H3), and the polymerization temperature. The catalysts are stable for hours under polymerization conditions (50 °C) in the highly disperse aqueous system.</dcterms:abstract> <bibo:uri rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:available rdf:datatype="">2011-03-22T17:55:10Z</dcterms:available> <dc:creator>Yu, Sze-Man</dc:creator> <dcterms:rights rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:bibliographicCitation>First publ. in: Macromolecules 42 (2009), 11, pp. 3669-3673</dcterms:bibliographicCitation> <dcterms:title>Variable crystallinity polyethylene nanoparticles</dcterms:title> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:date rdf:datatype="">2011-03-22T17:55:10Z</dc:date> <dcterms:issued>2009</dcterms:issued> <dc:creator>Mecking, Stefan</dc:creator> <dc:rights>terms-of-use</dc:rights> </rdf:Description> </rdf:RDF>
