Abstract
Mikto-arm star polymers were prepared comprising non-charged hydrophilic poly(ethylene oxide) arms and hydrophobic arms comprising a poly(propylene oxide) chain or phytol group. The polymer arms are covalently linked to a hydrophobic crosslinked polyester core formed by ring opening polymerization of a bis-cyclic ester initiated by mono-nucleophilic polymer arm precursors. The mikto-arm star polymers show improved loading capacity for Coenzyme Q10 (CoQ10).
