Neutron spin-echo experiments on poly(alkylene oxide)s with increasing side-group length have been focused on the decay of inter- and intradomain correlations and are complemented with molecular dynamics simulations on a coarse-grained model. In general, a good qualitative agreement between simulation and experiment is found. The collective times at inter- and intradomain levels converge with decreasing temperature, implying a common glass transition, and separate at high temperatures, revealing an increasing role of connectivity. The features of collective relaxations—regarding stretching, characteristic time, and temperature dependence—are independent of branching. The standard stretching for side-group motions and the closeness of collective and self-motions show that the anomalies exhibited by dynamically asymmetric comblike macromolecules disappear. 000818387 536__ $$0G:(DE-HGF)POF3-6215$$a6215 - Soft Matter, Health and Life Sciences (POF3-621)$$cPOF3-621$$fPOF III$$x0 000818387 536__ $$0G:(DE-HGF)POF3-6G15$$a6G15 - FRM II / MLZ (POF3-6G15)$$cPOF3-6G15$$fPOF III$$x1 000818387 588__ $$aDataset connected to CrossRef 000818387 65027 $$0V:(DE-MLZ)SciArea-210$$2V:(DE-HGF)$$aSoft Condensed Matter$$x0 000818387 65017 $$0V:(DE-MLZ)GC-1602-2016$$2V:(DE-HGF)$$aPolymers, Soft Nano Particles and Proteins$$x0 000818387 693__ $$0EXP:(DE-MLZ)J-NSE-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)J-NSE-20140101$$6EXP:(DE-MLZ)NL2ao-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eJ-NSE: Neutron spin-echo spectrometer$$fNL2ao$$x0 000818387 7001_ $$0P:(DE-HGF)0$$aMoreno, Angel J.$$b1 000818387 7001_ $$0P:(DE-Juel1)130501$$aAllgaier, J.$$b2$$ufzj 000818387 7001_ $$0P:(DE-Juel1)136923$$aIvanova, Oxana$$b3$$ufzj 000818387 7001_ $$0P:(DE-HGF)0$$aFouquet, Peter$$b4 000818387 7001_ $$0P:(DE-HGF)0$$aColmenero, Juan$$b5 000818387 7001_ $$0P:(DE-Juel1)130917$$aRichter, Dieter$$b6$$ufzj 000818387 773__ $$0PERI:(DE-600)1491942-4$$a10.1021/acs.macromol.6b00931$$gVol. 49, no. 13, p. 4989 - 5000$$n13$$p4989 - 5000$$tMacromolecules$$v49$$x1520-5835$$y2016 000818387 8564_ $$uhttps://juser.fz-juelich.de/record/818387/files/acs.macromol.6b00931.pdf$$yRestricted 000818387 8564_ $$uhttps://juser.fz-juelich.de/record/818387/files/acs.macromol.6b00931.gif?subformat=icon$$xicon$$yRestricted 000818387 8564_ $$uhttps://juser.fz-juelich.de/record/818387/files/acs.macromol.6b00931.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000818387 8564_ $$uhttps://juser.fz-juelich.de/record/818387/files/acs.macromol.6b00931.jpg?subformat=icon-180$$xicon-180$$yRestricted 000818387 8564_ $$uhttps://juser.fz-juelich.de/record/818387/files/acs.macromol.6b00931.jpg?subformat=icon-640$$xicon-640$$yRestricted 000818387 8564_ $$uhttps://juser.fz-juelich.de/record/818387/files/acs.macromol.6b00931.pdf?subformat=pdfa$$xpdfa$$yRestricted 000818387 909CO $$ooai:juser.fz-juelich.de:818387$$pVDB$$pVDB:MLZ 000818387 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130501$$aForschungszentrum Jülich$$b2$$kFZJ 000818387 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)136923$$aForschungszentrum Jülich$$b3$$kFZJ 000818387 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130917$$aForschungszentrum Jülich$$b6$$kFZJ 000818387 9131_ $$0G:(DE-HGF)POF3-621$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6215$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vIn-house research on the structure, dynamics and function of matter$$x0 000818387 9131_ $$0G:(DE-HGF)POF3-6G15$$1G:(DE-HGF)POF3-6G0$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G15$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vFRM II / MLZ$$x1 000818387 9141_ $$y2016 000818387 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000818387 915__ $$0StatID:(DE-HGF)0550$$2StatID$$aNo Authors Fulltext 000818387 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000818387 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bMACROMOLECULES : 2015 000818387 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bMACROMOLECULES : 2015 000818387 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000818387 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000818387 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000818387 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000818387 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000818387 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000818387 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000818387 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000818387 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000818387 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II$$lJCNS-FRM-II$$x0 000818387 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kNeutronenstreuung ; JCNS-1$$lNeutronenstreuung $$x1 000818387 980__ $$ajournal 000818387 980__ $$aVDB 000818387 980__ $$aUNRESTRICTED 000818387 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000818387 980__ $$aI:(DE-Juel1)JCNS-1-20110106
