摘要

The ability of poly(oxyalkylene) (POA) block copolymers to form micelles at low concentration has led to these structures being studied for their potential as carriers for novel and existing drugs~1. The amphiphilic nature of POA copolymers also allows them to circulate in the body for extended periods as a result of their avoidance of the reticuloendothelial system (RES)~2. POA copolymers also have potential in the solubilisation of hydrophobic drug substances and have been investigated for use in drug delivery forms~3. However, traditional diblock and triblock POA copolymer micelles have been found to be relatively poor solubilisers, a characteristic which has been attributed to the location of solubilised drugs at the hydrophobic/hydrophilic interface~4, and to their small size.
