Procedure

3 g SBS (the molecular weight is about 100,000; trade name is Taipol SBS-4202; manufactured by TSRC corp.) was fully dissolved in 60 ml cyclohexane. Adding a certain amount (0.7512 g) of mCPBA into the SBS solution and reacting at room temperature for 24 hrs. After reaction, the product was precipitated by 100 ml methanol for several times to be purified and isolated. According to H1-NMR determination, the transformation rate of double bond-epoxy group was about 2.1%, as shown in FIG. 1.
