PCL-PEG-PCL, PCL(1000)-PEG(4000)-PCL(1000)
PCL-PEG-PCL is an amphiphilic ABA triblock copolymer consisting of a hydrophilic block polyethylene glycol (PEG) and two hydrophobic block polycaprolactone. The hydrophobic blocks terminate with a hydroxyl group. Biocompatible PEGylated copolymers with biodegradable polyester segments can be used to prepare core-shell micelles, nanoparticles and microspheres. The molecular weight of each block is shown in the parenthesis following the name of each block.
