Reaction Conditions

Reaction Steps

Into a flask were charged 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 up to 75° C. under a nitrogen atmosphere. Into this solution was dropped a solution prepared by dissolving 11.05 g (0.048 mol) of dimethyl 2,2′-azobis(2-methylpropionate) in 22.11 g of isopropanol. The mixture was aged for about 0.3 hours at 75° C., and for about 12 hours under reflux, then, diluted with acetone. The reaction solution was poured into a large amount of methanol to precipitate a polymer which was filtrated. The amount of the resulted copolymer of 2-ethyl-2-admantyl methacrylate and p-acetoxystyrene was 250 g (weight of wet cake containing methanol).
