実験手順

Into a flask were charged 250 g of the copolymer of 2-ethyl-2-adamantyl methacrylate and p-acetoxystyrene (20:80) obtained in Synthesis Example 3, 10.3 g (0.084 mol) of 4-dimethylaminopyridine and 202 g of methanol, and aged for 20 hours under reflux. After cooling, the reaction liquid was neutralized with 7.6 g (0.126 mol) of glacial acetic acid and poured into a large amount of water to precipitate a polymer. The deposited polymer was filtrated, dissolved in acetone, then, poured into a large amount of water to cause precipitation, and this operation was repeated three times in total for purification.
