I. [Product Description]
COOH-PEG-PDLLA-PEG-COOH is an amphiphilic block copolymer, which combines the hydrophilicity of polyethylene glycol (PEG) and the hydrophobicity of poly(lactic-co-glycolic acid) (PDLLA). It can be used as a high-performance organic intermediate or pharmaceutical intermediate, suitable for the construction of nanocarriers, surface modification, and the development of functional materials. Its carboxyl terminal functional groups facilitate further chemical modification, enhancing the application flexibility of the material.

II. [Product Details]
