Hydrogen peroxide (30% aq solution, 68 μL, 0.6 mmol) was added to the mixture every 15 min for 5 times at room temperature under gentle stirring. After 2 h, the reaction mixture was poured into a large amount of methanol. The oily precipitates were separated by centrifugation, followed by drying in vacuo to give 1.0 g of polymer (yield 86%).
