実験手順
To a solution of poly(p-hydroxystyrene) (4.0 g) obtained in Synthesis Example 3, (2) and ethyl vinyl ether (1.5 g) in acetone, a catalytic amount of pyridinium p-toluenesulfonate was added, and reacted with stirring at room temperature for 12 hours. The reaction mixture was poured into H2O (1 liter) and was precipitated. The precipitate was filtered, washed with H2O and dried under reduced pressure to give 3.9 g of the desired product as a white powder having Mw 10000 (GPC with polystyrene calibration). The polymer was found to have p-(1-ethoxyethoxy)styrene unit and p-hydroxystyrene unit in a molar ratio of ca. 35:65 based on 1HNMR.
