PURPOSE: To obtain a resin composition exhibiting excellent moldability by improvement of fluidity, excellent in toughness, heat resistance, transparency and weather resistance and useful for household utensils, etc., by including an aromatic vinyl-based resin and a specific copolymer resin.
CONSTITUTION: This resin composition contains (A) an aromatic vinyl-based resin (B) a copolymer resin consisting essentially of (i) an aromatic vinyl-based monomer and (ii) a petroleum fraction containing a 5C hydrocarbon as a main component and/or a copolymer resin consisting essentially of the component (i) and (iii) an aliphatic polycyclic hydrocarbon monomer. Furthermore, the component A is preferably a styrenic resin having transparency and the component B is preferably a copolymer consisting of a styrenic monomer and the component (i).
