    • The present invention relates to a transparent thermoplastic resin composition which characteristically contains A) 20-80 weight % of graft copolymer composed of a) conjugated diene rubber latex; b) intermediate layer prepared by copolymerization of acrylic acid alkylester derivative and aromatic vinyl derivative with the above a); and c) graft layer prepared by copolymerization of methacrylic acid alkylester derivative or acrylic acid alkylester derivative, a romatic vinyl derivative and vinyl cyan derivative with the above b) and B) 20-80 weight % of MSAN copolymer prepared by copolymerization of methacrylic acid alkylester derivative or acrylic acid alkylester derivative, aromatic vinyl derivative and vinyl cyan derivative. The transparent thermoplastic resin composition of the present invention has enhanced transparency, impact strength, surface gloss, weather resistance and color by being prepared by the method of the invention which is characterized by the steps of forming an intermediate layer by adding acrylic rubber to polybutadiene rubber, grafting, and regulating refractive indices of each monomers of a copolymer.
    • 本发明涉及一种透明热塑性树脂组合物,其特征在于包含A)20-80重量%的由共轭二烯橡胶胶乳组成的接枝共聚物; b)通过丙烯酸烷基酯衍生物和芳族乙烯基衍生物与上述a)的共聚制备的中间层; 和c)通过甲基丙烯酸烷基酯衍生物或丙烯酸烷基酯衍生物,芳香族乙烯基衍生物和乙烯基氰基衍生物与上述b)和B)共聚制备的接枝层,其为通过甲基丙烯酸烷基酯共聚制备的20-80重量%的MSAN共聚物 衍生物或丙烯酸烷基酯衍生物,芳族乙烯基衍生物和乙烯基氰基衍生物。 本发明的透明热塑性树脂组合物通过本发明的方法制备透明性,冲击强度,表面光泽,耐候性和颜色,其特征在于以下步骤:通过向聚丁二烯橡胶中加入丙烯酸橡胶形成中间层 ,接枝和调节共聚物各单体的折射率。
