A racemic ansa-zirconocene complex that has a Si Cl moiety on its bridge was immobilized on SiO2 by the reaction of the Si Cl anchor with Si OH on the solid surface. The prepared solid catalyst was found to be effective for isospecific propene polymerization (catalyst A). Pretreatment of silica surfaces with Me3SiCl improved the catalyst performance (catalyst B). An ansa-zirconocene complex with a BH group reacted with vinyl-coated silica gel to afford another immobilized catalysts (catalyst C). This catalyst achieved satisfactorily high catalytic activity and high isotacticity in its produced polypropene.</dcterms:abstract> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:13:35Z</dcterms:available> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Nakamura, Takashi</dc:contributor> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/29"/> <dc:contributor>Fukuoka, Atsushi</dc:contributor> <dc:creator>Suzuki, Noriyuki</dc:creator> <dc:format>application/pdf</dc:format> <dc:creator>Wakatsuki, Yasuo</dc:creator> <dc:creator>Ichikawa, Masaru</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:13:35Z</dc:date> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:rights>deposit-license</dc:rights> <dcterms:bibliographicCitation>First publ. in: Applied Catalysis A 224 (2002), pp. 63-75</dcterms:bibliographicCitation> </rdf:Description> </rdf:RDF>
