실험 절차

A resin cook apparatus is charged with carbomethoxy-(2-hydroxyethyl)norbornene (50 grams, 0.26 mole), dimethyl adipate (13.3 grams, 0.076 mole), maleic anhydride (17.5 grams, 0.18 mole), NPG (29.2 grams, 0.28 mole), and dibutyltin oxide (0.22 grams). The mixture is heated at 180° to 190° C. for 7 hours. A conversion of 72 percent is obtained based on the methanol taken overhead.
