実験手順

15 g (3-acryloxypropyl)trimethylsiloxy silane, 40 g hydroxystyrene and 2.4 g AIBN were dissolved in 80 g THF and charged into a 3-neck flask. The system was then purged with N2 for 30 mins before the temperature was raised to 65° C. The reaction was carried out overnight under N2. On the second day, the solution was precipitated in 2000 mL water. The polymer was collected and dried in vacuum oven overnight at 40° C. The molecular weight was determined by GPC to be 9.1K and the molecular weight showed bimodal distribution.
