Mode opératoire

First, 176.3 g (1.0 mol) of p-tert-butoxystyrene and 16.2 g (0.105 mol) of cyclohexyl acrylate were dissolved in 250 ml of isopropanol. In a nitrogen stream, 2,2′-azobisisobutyronitrile was added to the solution, and agitated at 75° C. for six hours. The reaction liquid was cooled, and poured in 5000 ml of an aqueous solution of methanol, thereby precipitating a reaction product. The precipitated solid was collected by filtration, washed with methanol, and dried in vacuum. Thus, 172.5 g of poly(p-tert-butoxystyrene/cyclohexyl acrylate) was obtained as a white powdery crystal.
