To further elucidate the origin of this behavior, dilute aqueous solutions (5–10 mg mL−1) of these two copolymers have been investigated by small-angle neutron scattering (SANS), both in the absence and presence of PTX. Whereas PMeOx-b-PNOx-b-PMeOx forms mainly worm-like micelles coexisting with large aggregates, spherical micelles are predominant in PMeOx-b-PnBuOx-b-PMeOx. Already small PTX concentrations lead to shape changes in PMeOx-b-PNOx-b-PMeOx toward spherical micelles. In contrast, changes in the aggregation behavior of PMeOx-b-PnBuOx-b-PMeOx are only observed at higher PTX concentrations with a transformation into raspberry-like particles, which may explain the high PTX loading capacity of PMeOx-b-PnBuOx-b-PMeOx micelles.}, cin = {JCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II / Neutronenstreuung ; JCNS-1}, ddc = {540}, cid = {I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)JCNS-1-20110106}, pnm = {6G15 - FRM II / MLZ (POF3-6G15) / 6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)}, pid = {G:(DE-HGF)POF3-6G15 / G:(DE-HGF)POF3-6G4}, experiment = {EXP:(DE-MLZ)KWS1-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000380017700003}, doi = {10.1002/macp.201500465}, url = {https://juser.fz-juelich.de/record/824078}, }
