I. [Product Description] 
COOH-PEG-Polyacetal (Carboxyl-Polyethylene Glycol-Polyacetal) is a multifunctional amphiphilic block copolymer that combines the high water solubility and biocompatibility of polyethylene glycol (PEG) with the pH-responsive properties of polyacetal. This organic intermediate is widely used in polymer material synthesis, nanocarrier construction, and catalyst support systems. Its tunable molecular structure provides core value for the development of functional materials.
