We measure the ring form factor at θ- and good-solvent conditions as well as in a polymeric solvent (linear PS of roughly comparable molar mass) by means of small-angle neutron scattering (SANS). Additional dynamic light scattering (DLS) measurements support the SANS data and help elucidate the role of solvent quality and solution preparation. The results indicate the increase of ring dimensions as the solvent quality improves. Furthermore, the experimental form factors in both θ-solvent and linear matrix behave as ideal rings and are fully superimposable. The nearly Gaussian conformations of rings in a melt of linear chains provide evidence of threading of linear chains through rings. The latter result has implications for the dynamics of ring–linear polymer mixtures.}, cin = {ICS-1 / Neutronenstreuung ; JCNS-1}, ddc = {540}, cid = {I:(DE-Juel1)ICS-1-20110106 / I:(DE-Juel1)JCNS-1-20110106}, pnm = {551 - Functional Macromolecules and Complexes (POF3-551) / 6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623) / 6215 - Soft Matter, Health and Life Sciences (POF3-621)}, pid = {G:(DE-HGF)POF3-551 / G:(DE-HGF)POF3-6G4 / G:(DE-HGF)POF3-6215}, experiment = {EXP:(DE-MLZ)KWS1-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000350918700040}, doi = {10.1021/ma502518p}, url = {https://juser.fz-juelich.de/record/188468}, }
