摘要：
The poly(ε-caprolactone)-ethoxylated fatty acid copolymers are block copolymers including ε-caprolactone units and ethoxylated fatty alcohol units, the block copolymer having the structural formula:where n and m are integers greater than 0 and R is an alkyl group. The block copolymer is prepared by polymerizing ε-caprolactone and an ethoxylated fatty alcohol in the presence of a catalyst, such as stannous octoate. The block copolymers have potential as delivery systems for various payloads, such as, but not limited to, lipid soluble drugs and diagnostic agents.
