Procedure
The inside of a 500 ml-flask equipped with a nitrogen inlet tube and a cooling tube is replaced with a nitrogen gas. In the flask, placed are 100 g of styrene monomer (manufactured by Kishida Chemical Co., Ltd.); 100 g of butyl methacrylate (manufactured by Kishida Chemical Co., Ltd.); 200 ml of dehydrated dimethylformamide (manufactured by Kishida Chemical Co., Ltd.); and 20 g of azobisisobutyronitrile (manufactured by Kishida Chemical Co., Ltd.), from all of which dehydration treatment and removal of polymerization inhibitors have been conducted. After the inside of the flask is replacement with a nitrogen gas, the obtained mixture is heated to 80° C. and stirred for 5 hours. The resultant liquid is poured into a beaker containing 1 L of methanol for reprecipitation. The obtained solid product is cleaned with methanol, and heated and dried under vacuum to obtain 145 g of poly(styrene-butyl methacrylate) as a polymer.
