Abstract: The present invention describes the preparation of reverse polymeric micelles (RPM) through hydrophobically-modified star-shaped polyols. More specifically, RPM are obtained from polymeric structures where the polyol constitutes the hydrophilic domain while the hydrophobic shell is obtained either through the modification of existing chemical functions (e.g. esterification) or through copolymerization with hydrocarbon (alkyl)acrylate derivatives. Hydrophilic guests can be accommodated in the micelle core opening new avenues for the use of such carriers as delivery agents for polar active compounds.
