Conditions

Temperature: 110 °C

Procedure

With the addition of 2,2'-azobisisobutyronitrile, a mixture of styrene and n-butyl methacrylate at a mixing ratio of (75:25) was stirred at temperatures of 100 to 120° C. in order to obtain 43 parts by weight of a styrene-n-butyl methacrylate copolymer. The previously obtained solution was further added dropwise to the above polymerization mixture and the polymerization was allowed to continue for three hours. Thereafter, a solvent component was removed from the above mixture by heating under vacuum.
