Vorschrift

Next, 130.5 g of poly(p-tert-butoxystyrene/cyclohexyl acrylate) was suspended in isopropanol. Subsequently, 30 ml of concentrated hydrochloric acid was added to the suspension, and agitated at 70 to 80° C. for four hours. The reaction liquid was cooled, and poured in 1500 ml of water, thereby precipitating a reaction product. The precipitated solid was collected by filtration, washed with water, and dried in vacuum. Thus, 85.5 g of poly(p-hydroxystyrene/cyclohexyl acrylate) was obtained as a white powdery crystal.
