I. [Product Description] 
SS-PEG-PCL is a block copolymer containing disulfide bonds, which realizes controllable degradation characteristics through dynamic chemical bonds. It combines the hydrophilicity of PEG and the hydrophobicity of PCL, and can be used as a high-performance organic intermediate or pharmaceutical intermediate. It shows excellent modular design potential in the construction of nano-carriers and catalytic reaction systems.
