Reaction Conditions

Reaction Steps

In a reaction vessel, 133.37 g (0.6 mol) of 3-methoxy-4-(1-ethoxyethoxy)styrene and 119.35 g (0.4 mol) of (tert-butyl)-2,2′-[oxybis(methylene)]bis-2-propenoate were dissolved in 700 ml of tetrahydrofuran. While stirring the resulting solution, a nitrogen gas was passed into the system. Subsequently, 6.91 g (0.03 mol) of polymerization initiator V-601 (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-601 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 300 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 209.76 g of a 3-methoxy-4-(1-ethoxyethoxy)styrene/(tert-butyl)-2,2′-[oxybis(methylene)]bis-2-propenoate copolymer.
