Procedure

In a 200-liter reactor equipped with a stirrer, a cooling apparatus, a condenser and a monomer supplying tube, 5 parts by weight of butylacrylate, 15 parts by weight of styrene, 0.2 parts by weight of triallyl isocyanurate, 140 parts by weight of ion-exchanged water and 1.0 parts by weight of potassium rosinate are added and mixed. The temperature is raised to 60° C. with stirring. After 10 minutes from the time of reaching 60° C., 0.25 parts by weight of potassium persulfate dissolved in deionized water is added thereto to initiate polymerization. The temperature of the reactor is maintained at 70° C. for 60 minutes. The polymerization is carried out at 70° C. for an additional 30 minutes to give an inner core of butylacrylate-styrene copolymer.
