PROBLEM TO BE SOLVED: To obtain a styrene-based resin composition which enhances fabricability in vacuum forming and compressive air forming by the use of an extruded film of the styrene-based resin composition. SOLUTION: The thermoplastic resin composition is obtained by mixing a processing aid (B) for a styrene-based resin composed of a styrene-based polymer containing a styrene-based monomer unit of not less 60 mass %, the styrene-based polymer having a weight average molecular weight from more than 5,000,000 to less than 6,700,000 and Mw/Mn of not less than 2.5, with 100 pts.wt. of a styrene-based resin (A) containing a methyl ethyl ketone-soluble component having a weight average molecular weight of not more than 1,000,000. |
