Reaction Conditions

Reaction Steps

In a reaction vessel, 96.1 g (0.5 mol) of 3-methoxy-4-acetoxystyrene (produced by Honshu Chemical Industry Co., Ltd.) and 81.1 g (0.5 mol) of 4-acetoxystyrene (produced by Honshu Chemical Industry Co., Ltd.) were dissolved in 400 ml of tetrahydrofuran. While stirring the resulting solution, a nitrogen gas was passed into the system. Subsequently, 23.0 g (0.1 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, 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 600 ml of acetone and again added dropwise in 5 L of hexane and after filtration, the solid obtained was dried under reduced pressure to obtain 150.6 g of a (3-methoxy-4-acetoxystyrene)-(4-acetoxystyrene) copolymer.
