실험 절차
To 50 g (0.284 mole) of p-tert-butoxystyrene and 43.8 g (0.284 mole) of cyclohexyl acrylate was added 3 g of 2,2′-azobis(methyl 2-methylpropionate), followed by conducting a polymerization reaction in 1,4-dioxane under nitrogen gas streams at 80° C. for 6 hours. After cooling, the reaction solution was poured in 5000 ml of aqueous methanol solution to precipitate out. Crystal was recovered by filtration and dried under reduced pressure to give 89.2 g of poly(p-tert-butoxystyrene/cyclohexyl acrylate) as white powdery crystal. A weight-average molecular weight of the polymer was about 21000 by GPC measurement using polystyrene as a standard.
