実験手順

A solution of poly(p-hydroxystyrene) (8.0 g) [MARUKA LYNCUR-M, manufactured by Maruzene Petrochemical Co., Ltd., having Mw 10000 and Mn 5000], ethyl vinyl ether (3.0 g) and pyridinium p-toluenesulfonate (0.5 g) in dioxane (70 ml) was reacted with stirring at room temperature for 24 hours. After reaction, the mixture was poured into H2O, was precipitated with stirring, and the precipitate was filtered, washed with H2O and then dried in vacuo. There was obtained 10.0 g of the desired product as a white powder having Mw 11000 (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. 1:1 based on 1HNMR.
