実験手順

Poly(p-tert-butoxystyrene) obtained in the same manner as described in Production Example 1(1) in an amount of 15.0 g was suspended in isopropanol and added with 15 ml of concentrated hydrochloric acid. The reaction was carried out at 70° to 80° C. for 4 hours with stirring. After cooling, the reaction solution was poured into 1000 ml of water to deposit crystals. The deposited crystals were filtered, washed with water and dried under reduced pressure to give 9.4 g of white powdered crystals of poly(p-hydroxystyrene/p-tert-butoxystyrene). The proportion of the p-hydroxystyrene unit and the p-tert-butoxystyrene unit of the obtained polymer was about 30:64:6 measured by 1H NMR. Mw was about 17,500 and the degree of dispersion was 1.16 (GPC method, polystyrene standard).
