الإجراء التجريبي

Using 15.0 g of poly(p-hydroxystyrene/styrene) obtained according to (2) above and 3.2 g of vinylethyl ether, the procedure of (3) of Preparation Example 1 was carried out for reaction and after-treatments to give 14.1 g of poly(p-1-ethoxyethoxystyrene/p-hydroxystyrene/styrene) as white powdery crystals. P-1-ethoxyethoxystyrene unit/p-hydroxystyrene unit/styrene unit molar ratio in the polymer≈32:60:8 (1H NMR). Mw≈18,000; Mw/Mn≈1.85 (GPC with polystyrene calibration).
