Azobisisobutyronitrile → Bicyclo[2.2.1]hept-5-ene-2-methanol bicyclo[2.2.1]hept-5-ene-2-carboxylic acid norbornene maleic anhydride

참여 물질

반응 단계

To 70 ml of tetrahydrofuran was added 0.04 M of norbornylene, 0.1 M of bicyclo[2.2.1]hept-5-ene-2-methanol, 0.06 M of bicyclo[2.2.1]hept-5-ene-2-carboxylic acid, 0.2 M of maleic anhydride and 0.4 g of AIBN. The resulting solution was reacted at 67° C. for 8 hours. Thereafter, a polymer was precipitated and filtered in petroleum ether/ether (1/1) solution, to obtain the title polymer. Here, the polymer was washed with aqueous Na2CO3 solution (5%), and re-washed with distilled water to completely remove base. The resulting resin was vacuum-dried to obtain a pure resin (yield: 51%).
