Depending on the concentration of polymer and Ca<jats:sup>2+</jats:sup> and on the ratio of the block lengths in the copolymer, spherical micelles were observed. Micelle formation arises from the specific interaction of Ca<jats:sup>2+</jats:sup> with the PA block only. An extensive small-angle scattering study was performed in order to unravel the structure and dimensions of the block copolymer micelles. Deuteration of the PA block enabled us to perform contrast variation experiments using small-angle neutron scattering at variable ratios of light and heavy water which were combined with information from small-angle X-ray scattering and dynamic light scattering.</jats:p> Springer Science and Business Media LLC2020 eng Materials ChemistryColloid and Surface ChemistryPolymers and PlasticsPhysical and Theoretical Chemistry 0303-402X 1435-153610.1007/s00396-019-04596-1 2987663-679 Carl, N., Prévost, S., Schweins, R., &#38; Huber, K.
