Abstract:
1. A thermoplastic acrylonitrile-butadiene-styrene (ABS) resin composition comprising (a) 25 to 40 parts by weight of a bimodal graft copolymer of a conjugated diene rubbery polymer whose average particle diameter is from 800 to 1,500 Å and a conjugated diene rubbery polymer whose average particle diameter is from 2,500 to 3,500 Å, the conjugated diene rubbery polymers being grafted with an aromatic vinyl compound and a vinyl cyanide compound based on 100 parts by weight of a base resin composed of (a), (b) and (c), (b) 10 to 45 parts by weight of an acrylic resin of a methacrylic or acrylic acid alkyl ester compound, an aromatic vinyl compound and a vinyl cyanide compound based on 100 parts by weight of a base resin composed of (a), (b) and (c), (c) 50 to 65 parts by weight of a copolymer of an aromatic vinyl compound and a vinyl cyanide compound based on 100 parts by weight of a base resin composed of (a), (b) and (c), and (d) 0.5 to 5 parts by weight of masterbatches containing a polysiloxane whose viscosity is from 1,000,000 to 3,000,000 cSt, based on 100 parts by weight of a base resin composed of (a), (b) and (c).
