Epoxidation of Polyolefin by Peroxy Acid Generated in situ

The epoxidation of a new type polyolefin copolymer, poly(ethylene-co-1,9-decadiene) (PED) was carried out with performic acid produced in situ from formic acid and 35% hydrogen peroxide. The reaction was performed at room temperature or at 50 °C with conversion of vinyl group in the polymer chain and high selectivity to epoxide.
