More Information
Summary:The present invention discloses poly(2,2-dimethyl-trimethylenecarbonate)-polyglycol-poly(2,2- dimethyl-trimethylene carbonate) nano particle, its preparation method and application. Said invention uses polyglycol to initiate 5,5-dimethyl-trimethylenecarbonate monomer into ring-opening polymerization to synthesize amphiphilic triblock copolymer and obtain the correspondent core-shell type nano particles. Said invention also provides the characteristics of said nano particle with core-shell structure and its application in the pharmaceutical field.
