실험 절차

Maleic anhydride (1.0 mole), cis-5-norbornene-endo-2,3-dicarboxylic anhydride (0.2 mole), mono-methyl cis-5-norbornene-endo-2,3-dicarboxylate (0.15 mole) and tert-butyl-5-norbornene-2-carboxylate (0.65 mole) are dissolved in tetrahydrofuran. Then, 0.5 to 10 g of AIBN (azobisisobutyronitrile) as a polymerization initiator is added thereto, and the resultant mixture is reacted at about 60-70° C. for 4 to 24 hours under nitrogen or argon atmosphere. The polymer thus obtained is precipitated from ethyl ether or hexane, and dried to obtain the compound represented by the following Chemical Formula 101.
