Abstract
The invention provides a PCLm-PEG6000-PCLm thermo-sensitive self-assembled tri-block copolymer, wherein the copolymer presents two-phase transition characteristics, and can be applied to a controlled release drug delivery system as a drug carrier or can be applied to tissue engineering as a biodegradable material. The invention further provides a pharmaceutical composition containing the tri-block copolymer, and a preparation method and an application of the pharmaceutical composition. A system consisting of PCLm-PEG6000-PCLm tri-block copolymer and water can both load water-soluble drugs, and can efficiently load water-insoluble drugs, and has an excellent controlled-release effect.
