I. [Product Introduction]
COOH-PEG-PAA is an amphiphilic block copolymer that combines the chemical reactivity of carboxyl groups with the excellent biocompatibility of PEG segments. As a high-performance organic intermediate, it is widely used in the synthesis of nanomaterials and surface functional modification. Its unique molecular structure can precisely regulate the hydrophilic-lipophilic balance, and it has significant technical advantages in the fields of catalyst support construction and functional polymer assembly.
