Surprisingly, we find that in the melt phase the expected scaling of the Rouse dynamics is not satisfied. We propose an explanation based upon the large spatial volume occupied by the connecting groups. When the effects of these bulky groups on the local friction are taken into account, the usual scaling behavior is restored. 000052770 536__ $$0G:(DE-Juel1)FUEK414$$2G:(DE-HGF)$$aKondensierte Materie$$cP54$$x0 000052770 536__ $$0G:(DE-Juel1)FUEK415$$aGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$cP55$$x1 000052770 542__ $$2Crossref$$i2006-09-21$$uhttp://link.aps.org/licenses/aps-default-license 000052770 588__ $$aDataset connected to Web of Science 000052770 650_7 $$2WoSType$$aJ 000052770 7001_ $$0P:(DE-HGF)0$$aDubbeldam, J.
