Procedure

2-Methyl-2-adamantyl methacrylate, 2-norbornene and maleic anhydride were charged at a molar ratio of 4:3:3 (58.2 g:18.8 g:19.6 g). Thereto, tetrahydrofuran, the amount thereof being two times by weight based on the whole monomers, was added to form a monomer solution, followed by raising the temperature to 65° C. under nitrogen atmosphere. Then, was added azobisisobutyronitrile as an initiator in an amount of 3 mol % based on the whole monomer, and the resulting mixture was kept at 65° C. for 15 hours with stirring. Thereafter, the reaction mass was poured into a large amount of methanol to cause precipitation. This operation was repeated three times. A copolymer having a molecular weight of about 4710 and a molecular weight dispersion of 1.49 was obtained (61.9 g, yield 64.1%). This is called Resin AY.
