Selectively deuterating parts of the PMMA monomer, we have accessed five different partial structure factors in the glassy state by neutrons, and polarization analysis has allowed isolating the coherent contribution to the total scattering. In addition, the temperature dependence of the static structure factor has been determined on the fully deuterated sample. The different measured partial structure factors show qualitatively different features with respect to peak positions and heights and provide a very critical check to validate the simulated structure. To gain deep insight into the structure, we have grouped the simulation results in terms of three molecular substructures: the main chain, the alpha-methyl group, and the ester side group. The study of the resulting partial structure functions has revealed the origin of the diffraction peaks, including those in the X-rays pattern reported in the literature. In addition, a real-space evaluation of the characteristic radial distribution functions has allowed separating intra- and interchain contributions to the total correlation functions. We have found that (i) PMMA exhibits a strong local order with an average main-chain distance of approximate to 8.6 angstrom, ( ii) this is the only average interchain distance and thus no precursor effect of a layered structure is found, (iii) the main chain shows a persisting all-trans structure, and (iv) a strong anticorrelation between the main chain and the ester side groups, together with an interdigitation of the side groups, suggests a marked separation between the backbone and the side-group spatial arrangements. 000052533 536__ $$0G:(DE-Juel1)FUEK414$$2G:(DE-HGF)$$aKondensierte Materie$$cP54$$x0 000052533 536__ $$0G:(DE-Juel1)FUEK415$$aGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$cP55$$x1 000052533 588__ $$aDataset connected to Web of Science 000052533 650_7 $$2WoSType$$aJ 000052533 7001_ $$0P:(DE-HGF)0$$aArbe, A.$$b1 000052533 7001_ $$0P:(DE-HGF)0$$aAlvarez, F.$$b2 000052533 7001_ $$0P:(DE-HGF)0$$aColmenero, J.$$b3 000052533 7001_ $$0P:(DE-Juel1)130963$$aSchweika, W.$$b4$$uFZJ 000052533 7001_ $$0P:(DE-Juel1)130917$$aRichter, D.$$b5$$uFZJ 000052533 773__ $$0PERI:(DE-600)1491942-4$$a10.1021/ma060370t$$gVol. 39, p. 3947 - 3958$$p3947 - 3958$$q39<3947 - 3958$$tMacromolecules$$v39$$x0024-9297$$y2006 000052533 8567_ $$uhttp://hdl.handle.net/2128/1158$$uhttp://dx.doi.org/10.1021/ma060370t 000052533 8564_ $$uhttps://juser.fz-juelich.de/record/52533/files/82580.pdf$$yOpenAccess 000052533 8564_ $$uhttps://juser.fz-juelich.de/record/52533/files/82580.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000052533 8564_ $$uhttps://juser.fz-juelich.de/record/52533/files/82580.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000052533 8564_ $$uhttps://juser.fz-juelich.de/record/52533/files/82580.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000052533 909CO $$ooai:juser.fz-juelich.de:52533$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000052533 9131_ $$0G:(DE-Juel1)FUEK414$$bMaterie$$kP54$$lKondensierte Materie$$vKondensierte Materie$$x0$$zentfällt bis 2009 000052533 9131_ $$0G:(DE-Juel1)FUEK415$$bStruktur der Materie$$kP55$$lGroßgeräteforschung mit Photonen, Neutronen und Ionen$$vGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$x1 000052533 9141_ $$y2006 000052533 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000052533 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000052533 9201_ $$0I:(DE-Juel1)VDB342$$d31.12.2006$$gIFF$$kIFF-ISM$$lStreumethoden$$x0 000052533 9201_ $$0I:(DE-Juel1)VDB341$$d31.12.2006$$gIFF$$kIFF-INS$$lNeutronenstreuung$$x1 000052533 970__ $$aVDB:(DE-Juel1)82580 000052533 9801_ $$aFullTexts 000052533 980__ $$aVDB 000052533 980__ $$aJUWEL 000052533 980__ $$aConvertedRecord 000052533 980__ $$ajournal 000052533 980__ $$aI:(DE-Juel1)PGI-4-20110106 000052533 980__ $$aI:(DE-Juel1)ICS-1-20110106 000052533 980__ $$aUNRESTRICTED 000052533 980__ $$aFullTexts 000052533 981__ $$aI:(DE-Juel1)JCNS-2-20110106 000052533 981__ $$aI:(DE-Juel1)IBI-8-20200312 000052533 981__ $$aI:(DE-Juel1)JCNS-1-20110106 000052533 981__ $$aI:(DE-Juel1)PGI-4-20110106 000052533 981__ $$aI:(DE-Juel1)ICS-1-20110106
