Reaction Steps

The 5-norbornene-2-methanol/ethylene copolymer (18.4 g, 0.121 mol) that was polymerized in (2), 4-methoxy cinnamic acid (Aldrich, 21.5 g, 0.121 mol), EDC [1-(3-dimethylaminopropyl)-3-ethylcarboimide hydrochloride] (Aldrich, 37 g, 0.194 mol), and HOBT (1-hydroxybenzotriazole hydrate) (Aldrich, 24.5 g, 0.182 mol) were put into the 2-neck flask having the volume of 250 ml, and then dissolved in 100 ml of DMF. After the temperature was reduced to 0° C., triethylamine (Aldrich, 75 ml, 0.605 mol) was slowly dropped on the reaction solution. After the temperature was increased to normal temperature and maintained for 3 hours, when the reaction was finished, the reaction solution was dropped on a large amount of methanol to precipitate the polymer, and the polymer was filtered to obtain the 5-norbornene-2-methyl-(4-methoxy cinnamate)/ethylene copolymer to which the 4-methoxy cinnamoyl functional group was introduced (yield: 90.5%).
