Catalog No. : DL-3501k
Product Name : PEG-PLA, PEG MW 350 & PLA MW 1000
Description :

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). PEG-PLA with other MWs is also offered.
