実験手順

176.3, Gram (1.0, mol) of p-tert-butoxystyrene and 16.2 g (0.105, mol) of cyclohexyl acrylate were dissolved in 250 mL of isopropanol and in a nitrogen stream, 2,2′-azobisisobutyronitrile was added to the solution. The resulting mixture was stirred at 75° C. over 6 hours and after cooling, the reaction solution was poured in 5,000 mL of an aqueous methanol solution to precipitate the reaction product. The precipitated solid was collected by filtration, washed with methanol and dried under reduced pressure. In this way, 172.5 g of poly(p-tert-butoxystyrene/cyclohexyl acrylate) was obtained as a white powder crystal.
