PURPOSE: Provided is a thermoplastic ABS resin composition with excellent transparency and anti-shocking property by adding small amount of emulsified silicone oil after the completion of graft polymerization. CONSTITUTION: The method of making the composition comprises the steps of: mixing and stirring 10-70wt.% of rubber latex of diene rubber polymer with the average particle diameter of 0.05-0.5μm, 20-60wt.% of methacrylic alkylester monomer, 25-5wt.% of aromatic vinyl monomer, 0-10wt.% of unsaturated nitrile monomer, ion exchange water, emulsifier and initiator; graft polymerizing the mixture with keeping the reaction temperature at 40-80deg.C to make the latex; and adding 0.0001-0.05wt.% of silicone oil on the basis of the weight of the above graft polymer latex.
