실험 절차

A flask was charged with 39.7 g (0.16 mol) of 2-ethyl-2-adamantyl methacrylate, 103.8 g (0.64 mol) of p-acetoxystyrene and 265 g of isopropanol, and the mixture was heated to 75° C. under the nitrogen atmosphere. To the obtained solution was dropped a solution prepared by dissolving 11.05 g (0.048 mol) of dimethyl 2,2′-azobis(2-methylpropionate) into 22.11 g of isopropanol. After keeping the solution for about 0.3 hour at a temperature of 75° C. and then with stirring for 12 hours, the solution was diluted with acetone, and then the reaction solution was poured into a large amount of methanol to have a polymer precipitated, followed by filtration. Amount of thus obtained copolymer of 2-ethyl-2-adamantyl methacrylate and p-acetoxystyrene was 250 g (note: that this is a weight of a wet cake containing methanol).
