I. [Product Description]
SS-PEG-PEI is a dynamic responsive polymer complex containing disulfide bonds. It achieves multi-functionality through the precise coupling of polyethylene glycol (PEG) and polyethyleneimine (PEI), combining the biocompatibility of PEG and the cationic properties of PEI. As a high-performance organic intermediate, this compound is widely used in polymer material modification, nanocarrier construction, and optimization of catalytic reaction systems. Its disulfide bond structure endows the product with controllable degradation ability, meeting the requirements of complex chemical environments.
