I. [Product Description]
VA-PEG-P4VP (Valeric acid-Polyethylene glycol-Poly(4-vinylpyridine)) is an amphiphilic block copolymer, which combines the synergistic action of a hydrophobic segment (P4VP) and a hydrophilic segment (PEG). It can be used as an organic intermediate or pharmaceutical intermediate in the construction of nanocarriers and the preparation of functional materials. Its unique self-assembly properties and pH-responsive ability enable it to exhibit excellent carrier compatibility and controlled release potential in catalytic reaction systems.
