摘要
The triarmed polyethylene oxide-deoxycholic acid (PEO-DC) was synthesized by the introduction of a triol group to the end of the PEO chain and by a subsequent coupling reaction with deoxycholic acid. These polymeric amphiphiles formed were stable and the spherical micelles in aqueous media have a unimodal size distribution. The triarmed PEO-DC conjugate formed micelles of smaller size at a lower critical micelle concentration than those of monosubstituted ones. This was considered to result from an increase in hydrophobicity of the triarmed conjugate.
