I. [Product Description] 
PEG-TK-PS (Polyethylene Glycol-Ketal Thiol-Polystyrene) is a multifunctional organic intermediate. Through a precisely designed block copolymer structure, it combines the hydrophilicity of polyethylene glycol and the hydrophobicity of polystyrene. Its core value lies in the dynamic reversible property of the ketal thiol bond, which can be used as an efficient catalyst carrier or a precursor for responsive materials, and is widely applied in the fields of polymer synthesis and functional modification.
