    摘要： The present invention relates to a method for preparing a weather resistant reinforced acrylate based resin. More specifically, an activator-free conversion rate improver is included in an acrylate-styrene based graft copolymer, thereby improving the haze value, light transmittance, and yellow index when mixed with an acrylate-styrene based non-graft copolymer, and securing the weather resistance. In particular, according to the present invention, a weather resistant reinforced thermoplastic resin having excellent colors which are close to natural colors can be provided even without using sodium formaldehyde sulfoxylate (SFS) and iron ions.

    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.
