To provide a thermoplastic resin composition excellent in weatherability, impact resistance and appearance.
The thermoplastic resin composition comprises (I) 50-90 mass% of the continuous phase described below and (II) 10-50 mass% of the disperse phase described below. In this composition, the weight-average molecular weight of the continuous phase is 60,000-200,000 and the volume-average particle size of the disperse phase is 0.3-1.5μm and the graft percentage is ≥20%; wherein, the continuous phase(I) consists of a styrene-(meth)acrylic ester-based copolymer made from a styrene-based monomer, a (meth)acrylic ester-based monomer and optionally a vinyl monomer copolymerizable therewith, and the disperse phase(II) consists of a polymer obtained by grafting a styrene-(meth)acrylic ester-based copolymer made from a styrene-based monomer, a (meth)acrylic ester-based monomer and optionally a vinyl monomer copolymerizable therewith to a polyolefin-based rubbery elastomer ≤-30°C in glass transition temperature.
