Abstract
A thermoplastic acrylonitrile-butadiene-styrene (ABS) resin composition of the present invention comprises (a) a bimodal graft copolymer of a conjugated diene rubbery polymer whose average particle diameter of 800 to 1,500 Å and a conjugated diene rubbery polymer whose average particle diameter of 2,500 to 3,500 Å, the conjugated diene rubbery polymers being grafted with an aromatic vinyl compound and a vinyl cyanide compound, (b) an acrylic resin of a methacrylic or acrylic acid alkyl ester compound, an aromatic vinyl compound and a vinyl cyanide compound, (c) a copolymer of an aromatic vinyl compound and a vinyl cyanide compound, and (d) polysiloxane masterbatches. The ABS resin composition has excellent colorability and releasability while maintaining the inherent physical properties (e.g., impact strength and tensile strength) of the base resin.
