In a reaction vessel, 111.14 g (0.5 mol) of 3-methoxy-4-(1-ethoxyethoxy)styrene and 94.59 g (0.5 mol) of N-(4-hydroxyphenyl)maleimide were dissolved in 400 ml of tetrahydrofuran. While stirring the resulting solution, a nitrogen gas was passed into the system. Subsequently, 12.42 g (0.05 mol) of polymerization initiator V-65 (produced by Wako Pure Chemical Industries, Ltd.) was added thereto and the reaction solution was heated at 65° C. After stirring under heat for 10 hours by adding V-65 in the same amount as above every one hour, the reaction solution was allowed to cool to room temperature and then added dropwise in 5 L of hexane to precipitate a polymer. The solid obtained by filtration was dissolved in 800 ml of tetrahydrofuran and the resulting solution was again added dropwise in 5 L of hexane. After filtration, the solid obtained was dried under reduced pressure to obtain 181.04 g of a 3-methoxy-4-(1-ethoxyethoxy)styrene/N-(4-hydroxyphenyl)maleimide copolymer.
