실험 절차

Di-tert-butyl 5-norbornene-2,3-dicarboxylate (0.85 mole), 3-hydroxypropyl 5-norbomene-2-carboxylate (0.1 mole), 5-norbomene-2,3-dicarboxylic acid (0.05 mole) and maleic anhydride (1 mole) were mixed together in tetrahydrofuran solvent, and AIBN (5.5 g) was added to the mixture as a polymerization initiator. Polymerization was performed under nitrogen atmosphere for 10 hours while maintaining the temperature at 67° C. When the polymerization was completed, the polymer was precipitated from ethyl ether and dried in vacuo to obtain pure poly(di-tert-butyl 5-norbornene-2,3-dicarboxylate/3-hydroxypropyl 5-norbornene-2-carboxylate/5-norbornene-2,3-dicarboxylic acid/maleic anhydride) of Chemical Formula 107 shown above (yield: 30%).
