摘要：
Amphiphilic star polymers were prepared having superior loading properties for delivery of hydrophobic biologically active materials intended for use in medical, cosmetic, and other applications. The star polymers comprise a plurality block copolymer arms linked to a crosslinked polyester core. The monovalent arms comprise a peripheral poly(ethylene oxide) block (PEG block) and a polyester block, which is linked to the core. The sidechain substituents of the polyester block substantially improve the loading capacity of the star polymer for CoQ10 and other hydrophobic materials.
