To this purpose, thermosensitive core-shell particles consisting of a polystyrene core and a cross-linked poly(N-isopropylacrylamide) shell were synthesized. Data over an extended range in shear rates and frequencies are compared to theoretical results from integrations through transients and mode coupling approaches. The connection between nonlinear rheology and glass transition is clarified. While the theoretical models semiquantitatively fit the data taken in fluid states and the predominant elastic response of glass, a yet unaccounted dissipative mechanism is identified in glassy states.</dcterms:abstract> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-22T17:51:53Z</dc:date> <dc:creator>Fuchs, Matthias</dc:creator> <dc:creator>Henrich, Oliver</dc:creator> <dc:creator>Hajnal, David</dc:creator> <dc:contributor>Ballauff, Matthias</dc:contributor> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
