Procedure

Placed in a 1-liter capacity round reaction vessel were 400 g of deionized water, 3.6 g gum Arabic, and 3.6 g of lignosulfonic acid, and the vessel was set in a water bath. Then said vessel was equipped with a stirring device, a Dimroth condensing pipe, a dripping device, and a nitrogen supplying tube, and the resulting mixture was subjected to nitrogen bubbling while stirring, and was heated to 80° C. Thereafter, the nitrogen bubbling was replaced with a nitrogen gas flow, and a mixed monomer solution comprised of 81.2 g of styrene monomer, 18.8 g of n-butyl acrylate monomer, 25 g of methyl methacrylate monomer, and 0.6 g of benzoyl peroxide was added dropwise, and suspension polymerization was then carried out. After 18 hours, the reaction product was removed, washed with water, and filtered. The resulting reaction product was then dried. Thus styrene-n-butyl acrylate-methyl methacrylate copolymer (St-BA-MMA copolymer) was obtained as Compatibilizer S-1.
