Procedure
Using 11.4 g of poly(p-hydroxystyrene/p-tert-butoxycarbonyloxystyrene) obtained according to (2) above and 2.5 g of ethylvinyl ether, the procedure of (3) of Preparation Example 1 was carried out for reaction and after-treatments to obtain 6.7 g of poly(p-1-ethoxyethoxystyrene/p-hydroxystyrene/p-tert-butoxycarbonyloxystyrene) as white powdery crystal. P-1-ethoxyethoxystyrene unit/p-hydroxystyrene unit/p-tert-butoxycarbonyloxystyrene unit molar ratio in the polymer≈30:64:6 (1H NMR). Mw≈20,000; Mw/Mn=1.90 (GPC with polystyrene calibration).
