The data reveal a very compact conformation displaying a structure approaching a mass fractal, as hypothesized by recent simulation work. The dynamics is characterized by a fast Rouse relaxation of subunits (loops) and a slower dynamics displaying a lattice animal-like loop displacement. The loop size is an intrinsic property of the ring architecture and is independent of molecular weight. This is the first experimental observation of the space-time evolution of segmental motion in ring polymers illustrating the dynamic consequences of their topology that is unique among all polymeric systems of any other known architecture.}, cin = {ICS-1 / JCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II / Neutronenstreuung ; JCNS-1}, ddc = {550}, cid = {I:(DE-Juel1)ICS-1-20110106 / I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)JCNS-1-20110106}, pnm = {451 - Soft Matter Composites (POF2-451) / 54G - JCNS (POF2-54G24)}, pid = {G:(DE-HGF)POF2-451 / G:(DE-HGF)POF2-54G24}, experiment = {EXP:(DE-MLZ)KWS1-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000344032500011}, doi = {10.1103/PhysRevLett.113.168302}, url = {https://juser.fz-juelich.de/record/171701}, }
