Description

PLGA-PEG-COOH (Poly(lactide-co-glycolide)-b-Poly(ethylene glycol)-Carboxylic acid) is a diblock copolymer with an acid group at the distal end of PEG. PEG-PLGA is an amphiphilic AB diblock copolymer consisting of a hydrophilic block polyethylene glycol (PEG) or polyethylene oxide (PEO) and a hydrophobic block poly(lactide-co-glycolide) (PLGA). The hydrophobic block terminates with a hydroxyl group. PEGylated copolymers with biodegradable and biocompatible polyester segments is useful 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). LA/GA molar ratio will be 1:1 with no request. Specified molecular weight and molecular ratio may be offered by custom synthesis. Please contact us for more details.
