PLA-PEG

Polylactic acid-polyethylene glycol,PLA-PEG from ruixi.PEG-PLA is an amphiphilic AB diblock copolymer consisting of a hydrophilic block polyethylene glycol (PEG) or polyethylene oxide (PEO) and a hydrophobic block polylactic acid or polylactide (PLA). The PEG polymer is capped a methyl ether group, and the hydrophobic block terminates with a hydroxyl group. PEGylated copolymers with biodegradable and biocompatible polyester segments can be used to prepare core-shell micelles, nanoparticles and microspheres. The hydrolytic degradability of polyester segments depend on the molecular weight and the spacer between ester groups (lactide, glycolide or caprolactone).
