Reaction Conditions

Reaction Steps

Into a flask were added 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, followed by heating up to 75° C. under an atmosphere of nitrogen. To this solution was dropped a solution of 11.05 g (0.048 mol) of dimethyl 2,2′-azobis(2-methylpropionate) dissolved in 22.11 g of isopropanol. The solution was heated for about 0.3 hour at 75° C. and further refluxed for about 12 hours. After diluting with acetone, the reaction mixture was poured into a large amount of methanol to precipitate the polymerized product, which was separated by filtration. The weight of the obtained copolymer of 2-ethyl-2-adamantyl methacrylate and p-acetoxystyrene was 250 g (note: wet weight of cake containing methanol).
