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.
制备出的两亲星型聚合物具有优异的负载性能,可用于输送疏
水性
生物活性材料,供医疗、化妆品和其他应用使用。星型聚合物由多个嵌段共聚物臂组成,嵌段共聚物臂与交联聚酯芯相连。单价臂包括外围的聚
环氧乙烷嵌段(P
EG 嵌段)和与核心相连的聚酯嵌段。聚酯嵌段的侧链取代基大大提高了星形聚合物对 CoQ10 和其他疏
水性材料的负载能力。
