Procedure

To 25 ml of tetrahydrofuran in 100 ml of a round-shaped flask were added 5 g of 3-(trimethoxysilyl)propyl methacrylate, 4 g of t-butyl methacrylate, 3 g of methyl 5-norbornene-2-carboxylate and 3 g of maleic anhydride. Then, 0.13 g of AIBN (azobisisobutyronitrile) as a polymerization initiator was added to the resulting mixture, and reacted at 67° C. under a nitrogen atmosphere for 24 hours. Next, the resulting mixture was cooled at room temperature, and poured into a beaker including 500 ml of ethyl ether to precipitate the resulting mixture. Thereafter, the precipitate was filtered and dehydrated at room temperature, thereby obtaining poly(3-(trimethyoxysilyl)propyl methacrylate/t-butyl methacrylate/methyl 5-norbornene-2-carboxylate/maleic anhydride) having a molecular weight of 1,800 represented by formula 1a (yield: 50%).
