Preparation of Degradable Hyperbranched Polystyrene Homopolymers with Cleavable Disulfide Linkages

5 Preparation of Degradable Hyperbranched Polystyrene Homopolymers with Cleavable Disulfide Linkages 

Using Seesaw-type macromonomer =-S-S-(PS-N3)2 with one clevable disulfide linkage at the chain center, we successfully prepared degradable hyperbranched polystyrene chains with uniform subchains and contfolled locations of cleavable disulfide linkages (Fig. 4.25).
