TRANSPARENT ABS RESIN COMPOSITION HAVING SUPERIOR SHOCK RESISTANCE, SCRATCH RESISTANCE, AND TRANSPARENCY

摘要

A transparent ABS resin composition according to the present invention comprises: (a) an acrylon itrile butadiene styrene (g-ABS) in which a mixture (a2) of an acrylate monomer, a styrene monomer, and an acrylonitrile monomer are co-polymerized on a butadiene-based rubber copolymer (a1); and (B) a styrene-acrylonitrile copolymer, and satisfies a relationship represented by mathematical formulae 1 and 2 below, wherein the transparent ABS resin composition has superior shock resistance, scratch resistance, and superior transparency. (Mathematical formula 1) 0≤｜X-Y｜≤ 0.005 (Mathematical formula 2) 0≤｜X-Z｜≤ 0.005, wherein X represents the refractive index of the acrylonitrile butadiene styrene (g-ABS) copolymer (A), Y represents the refractive index of the butadiene-based rubber copolymer (a1); and Z represents the refractive index of the styrene-acrylonitrile copolymer (B).
