Procedure

50 parts of butadiene rubber latex powder, 36 parts of styrene, 14 parts of acrylonitrile, and 150 parts of deionized water were blended. To the blend, 1.0 parts of potassium oleate, 0.4 parts of cumenhydroperoxide, 0.2 parts of mercaptan-containing chain transfer agent, 0.4 parts of glucose, 0.01 parts of ferrous sulfate hydrate, and 0.3 parts of sodium pyrophosphate were added. The blend was kept at 75° C. for 5 hours to obtain g-ABS latex. To the g-ABS latex, 0.4 parts of sulfuric acid was added, coagulated and dried to obtain acrylonitrile-butadiene-styrene graft copolymer resin (g-ABS) in a powder form.
