Reaction Steps

2-ethyl-2-adamantyl methacrylate, 3-hydroxy-1-adamantyl acrylate and α-methacryloyloxy-γ-butyrolactone were charged in a molar ratio of 2:1:1 (20.0 g:8.9 g:6.5 g), and methyl isobutyl ketone of twice weight of the total monomer weight was added to this to prepare a solution. To this was added azobisisobutyronitrile as an initiator in an amount of 2 mol % based on the total monomer amount, and the temperature was raised to 85° C. and the mixture was stirred for about 5 hours. The reaction mass was cooled, then, poured into a large amount of heptane, to cause precipitation; this operation Was repeated three times for purification. As a result, a copolymer having a weight-average molecular weight of about 8000 was obtained in a yield of 60%. This resin is called Resin AX.
