Propyl maleimide (1 mol.), t-butyl 5-norbornene-2-carboxylate (0.5 mol.) and 2-hydroxyethyl bicyclo[2,2,2]oct-5-ene-2-carboxylate (0.5 mol) were dissolved in 50 g to 300 g of tetrahydrofuran (THF), 2 g to 15 g of 2,2′-azobisisobutyronitrile (AIBN) was added thereto, and the resulting solution was reacted at a temperature between 60° C. and 70° C. in a nitrogen atmosphere for 10 hours. After a high molecular weight was achieved by the reaction, the resultant product was precipitated in an ethyl ether or hexane solvent. The gathered precipitate was dried, and the desired poly(propyl maleimide/t-butyl 5-norbornene-2-carboxylate/2-hydroxyethyl bicyclo[2,2,2]oct-5-ene-2-carboxylate) polymer was obtained at a yield of about 79%.
