I. [Product Description]
PEG-ss-PEI (Polyethylene Glycol-Disulfide Bond-Polyethyleneimine) is an amphiphilic block copolymer with redox responsiveness. It combines the hydrophilic modification ability of PEG and the cationic properties of PEI, and can be used as an efficient organic intermediate and pharmaceutical intermediate. Its unique disulfide bond structure endows the material with environmental responsiveness and shows excellent performance in the fields of catalyst loading and controlled release.
