Procedure

130.5, Gram of poly(p-tert-butoxystyrene/cyclohexyl acrylate) was suspended in isopropanol, and 30 mL of concentrated hydrochloric acid was added to the suspension. This mixture was stirred at 70 to 80° C. over 4 hours and after cooling, the reaction solution was poured in 1,500 mL of water to precipitate the reaction product. The precipitated solid was collected by filtration, washed with water and dried under reduced pressure. In this way, 85.5 g of poly(p-hydroxystyrene/cyclohexyl acrylate) was obtained as a white powder crystal.
