Abstract:
The present invention relates to: a polystyrene resin composition which is characterized by having excellent stiffness, impact resistance and fluidity (injection moldability); and a method for producing this polystyrene resin composition. The present invention provides: a polystyrene resin composition which contains (A) 95-60 parts by mass of a polystyrene resin, (B) 5-40 parts by mass of an ethylene elastomer and (C) 1-20 parts by mass of a cross copolymer per 100 parts by mass of the total of the component (A) and the component (B); and a method for producing this polystyrene resin composition. Since this polystyrene resin composition is of saturated type, this polystyrene resin composition has a good balance between impact resistance (elongation) and stiffness.
