I. [Product Description]
COOH-PEG-PS (Carboxyl-Polyethylene Glycol-Polystyrene) is a multifunctional block copolymer that combines the hydrophilicity of polyethylene glycol and the hydrophobicity of polystyrene. It is a core organic intermediate for preparing nanomicelles and drug carriers. Its carboxyl reactive groups enable precise functional modification and show excellent application potential in the fields of catalyst loading and polymer self-assembly.
