A glass ampule having a volume of 75 mL was charged with 50 g (0.25 mol) of diisopropyl fumarate, 6.5 g (0.044 mol) of cinnamic acid and 0.32 g (0.0018 mol) of tert-butyl peroxypivalate as a polymerization initiator and after repeating purging with nitrogen and release of the pressure, sealed in the pressure-reduced state. This ampule was placed in a constant temperature bath at 50° C. and held for 48 hours, thereby performing radical polymerization. After the completion of polymerization reaction, the polymerization product was taken out of the ampule and dissolved in 400 g of tetrahydrofuran. The resulting polymer solution was added dropwise, for precipitation, to 3 L of methanol, and the precipitate was vacuum-dried at 80° C. for 10 hours to obtain 19 g of a diisopropyl fumarate/cinnamic acid copolymer (yield: 34%).
