実験手順

In a reaction vessel, 96.1 g (0.5 mol) of 3-methoxy-4-acetoxystyrene (manufactured by Honshu Chemical Industry Co., Ltd.) and 81.1 g (0.5 mol) of 4-acetoxystyrene (manufactured by Honshu Chemical Industry Co., Ltd.) are dissolved in 400 ml of tetrahydrofuran, and nitrogen gas is streamed to the reaction solution while stirring. To the solution is added 23.0 g (0.1 mol) of polymerization initiator V-601 (manufactured by Wako Pure Chemical Industries), and the reaction solution is heated at 65° C. After stirring for 10 hours, the reaction solution is allowed to cool to room temperature and then dropped into 5 liters of hexane to precipitate a polymer. A filtered solid is dissolved in 600 ml of acetone, dropped again into 5 liters of hexane and a filtered solid is dried under reduced pressure to obtain 150.6 g of a (3-methoxy-4-acetoxystyrene)-(4-acetoxystyrene) copolymer.
