The present invention relates to a styrenic resin composition having excellent chemical resistance to a specific blowing agent, a process for producing the styrenic resin composition, and a molded article comprising the same. More particularly, the present invention relates to a styrenic resin composition comprising an ABS resin containing a diene rubber polymer having an average particle diameter of 0.1 to 0.5 μm Graft copolymer, a rubber-modified graft copolymer containing a diene rubber polymer having an average particle diameter of 0.5 to 10 mu m, an ASA-based graft copolymer and an aromatic vinyl chemical-vinyl cyanide copolymer Based on the weight of the polyester-based elastomer, a method for producing the same, and a molded article thereof. The sheet extruded with the styrene resin composition according to the present invention has a tensile strength and an elongation retention ratio of 100% before and after the chemical resistance (ESCR) test for a foaming agent containing a fluoroalkene compound and has excellent chemical resistance, And has suitable properties as an extruded sheet. |
