Procedure
Using 26.8 g of poly(p-hydroxystyrene/p-tert-butoxystyrene) obtained according to (2) above and 1.5 g of ethylvinyl ether, reaction and after-treatments were carried out according to (3) of Preparation Example 1 to obtain 25.0 g of poly(p-1-ethoxystyrene/p-hydroxystyrene/p-tert-butoxystyrene) as white powdery crystal. P-1-ethoxyethoxystyrene unit/p-hydroxystyrene unit/p-tert-butoxystyrene unit molar ratio in the polymer≈10:65:25. Mw≈1 9,200; Mw/Mn=1.30 (GPC with polystyrene calibration).
