-6 Å -2 and therefore almost perfectly in between the SLDs of A-pBuOzi-A and D 2 O (Table ), suggesting that the ratio of A-pBuOzi-A/D 2 O is roughly 1/1. In other words, these micelles do not exhibit a core-shell structure but are rather homogenous in composition, which we tentatively attribute to excellent hydration of the hydrophobic repeat units by virtue of the polar and flexible poly(2-oxazine) backbone. By adding CUR (CUR = 1 g/L), SLD core decreases slightly (Figure , A), which could be an indication of the dehydration of the core in favor of CUR inclusion. The SLD of the first shell is slightly above the initial value of the spherical aggregates (roughly 4x10 -6 Å -2
