PCL(5k)-PEG(5k)-N3 is a block copolymer containing polycaprolactone (PCL) block (hydrophobic) and PEG block (hydrophilic). In aqueous media, the polymer self-assembles to form micelles with PCL core and PEG shell. The core can be used as reservoir for hydrophobic drugs while the shell can provide protection from degradation (enzymatic/hydrolysis). The terminal azide is reactive with DBCO/BCN or terminal alkyne in the presence of copper catalyst. Reagent grade, for research purpose.
