    摘要： The present invention provides a transparent acrylonitrile-butadiene-styrene (ABS) resin and a transparent ABS resin composition. Specifically, according to the present invention, a transparent ABS resin and a transparent ABS resin composition, which have excellent transparency and impact resistance, can be provided by minimizing the degree of impregnation of a styrene monomer into a polybutadiene rubber latex while allowing the styrene monomer to constitute a graft shell to thereby effectively form the graft shell. Particularly, according to the present invention, a transparent ABS resin composition having high transparency and impact resistance can be provided, despite applying a reducing agent and Fe ions, which adversely affected the transparency of ABS resin in the prior art, to ABS resin.

    摘要翻译： 本发明提供透明的丙烯腈 - 丁二烯 - 苯乙烯（ABS）树脂和透明ABS树脂组合物。 具体地说，根据本发明，通过使苯乙烯单体在聚丁二烯橡胶胶乳中的浸渍程度最小化，同时使苯乙烯单体成为可能，可以提供具有优异的透明性和耐冲击性的透明ABS树脂和透明ABS树脂组合物 以构成移植物壳，从而有效地形成移植物壳。 特别地，根据本发明，尽管将现有技术中的ABS树脂的透明度不利地影响到ABS树脂，但是还可以提供具有高透明性和耐冲击性的透明ABS树脂组合物。

    摘要： Provided is a method of preparing a graft polymer, which includes: adding a diene-based rubber polymer, a first monomer mixture including a (meth)acrylate-based monomer and an aromatic vinyl-based monomer, and a reactive ultraviolet (UV) stabilizer to a reactor and carrying out polymerization to prepare a composite rubber polymer; and graft-polymerizing a second monomer mixture including a (meth)acrylate-based monomer, an aromatic vinyl-based monomer, and a vinyl cyanide-based monomer to the composite rubber polymer to prepare a graft polymer, wherein the reactive UV stabilizer is added in an amount of 0.1 to 2 parts by weight based on 100 parts by weight of the sum of the diene-based rubber polymer, the first monomer mixture, and the second monomer mixture.

    摘要： The present invention provides a thermoplastic resin composition which includes: A-1) a first copolymer including a first conjugated diene-based polymer, an alkyl (meth)acrylate-based monomer unit, and an aromatic vinyl-based monomer unit, wherein the first conjugated diene-based polymer has an average particle diameter of 0.05 to 0.2 μm; A-2) a second copolymer including a second conjugated diene-based polymer, an alkyl (meth)acrylate-based monomer unit, and an aromatic vinyl-based monomer unit, wherein the second conjugated diene-based polymer has an average particle diameter of 0.23 to 0.5 μm; B) a third copolymer including an alkyl (meth)acrylate-based monomer unit and an aromatic vinyl-based monomer unit; and C) a plasticizer having a viscosity of 700 to 10,000 cP, wherein the plasticizer is included at 0.3 to 5 wt %. The thermoplastic resin composition is excellent in all of transparency, impact resistance, and flowability.
