The formation of “hairy-type” and “flower-like” micelles was established in dilute aqueous and aqueous/ethanol solutions. The “hairy” micelles contained a “core” comprised cooperatively interacting PEO and PAAm segments and “corona” formed by unbound units of longer PAAm blocks. Appearance of the “flower-like” micelles was conditioned by insolubility of PAAm blocks. Stability of the “flower-like” micelles was higher than that of the "hairy-type" ones. Significant encapsulation of a model drug prednisolon by TBC micelles was established.
