Description
PLA-PEG-PLA is an amphiphilic ABA triblock copolymer consisting of a hydrophilic block polyethylene glycol (PEG) and two hydrophobic block polylactide. The hydrophobic blocks terminate with hydroxyl group. Biocompatible PEGylated copolymers with biodegradable polyester segments is useful to prepare core-shell micelles, nanoparticles and microspheres. The molecular weight of each block is present in the parenthesis following the name of the block.
