I. [Product Description]
EDA-PEG-PS Diamine-Polyethylene Glycol-Polystyrene is a multifunctional organic intermediate that combines the hydrophilicity of polyethylene glycol (PEG) with the hydrophobicity of polystyrene (PS). It can be used as an efficient catalyst support or pharmaceutical intermediate. Its unique block structure endows it with excellent phase transfer performance and is widely used in the fields of polymer material synthesis and functional modification.
