摘要： The present invention provides a thermoplastic resin composition for a vehicular lamp housing, which is excellent in balance of physical properties with regard to such as impact resistance and fluidity, and of which hot plate weldability, vibration weldability and laser weldability are improved when a vehicular lamp housing is welded with other members.A thermoplastic resin composition for a vehicular lamp housing, comprising a graft copolymer (A) and a (co)polymer (C) is provided, wherein the graft copolymer (A) is obtained by emulsion graft polymerization of an acrylic acid ester-based rubbery polymer having a weight average particle diameter of 70 to 250 nm with at least one monomer selected from the group consisting of an aromatic vinyl-based monomer, a vinyl cyanide-based monomer, a (meth)acrylic acid ester-based monomer and a maleimide-based monomer, wherein the acrylic acid ester-based rubbery polymer is obtained by emulsion polymerization of 60 to 95% by weight of an acrylic acid ester-based monomer in the presence of 5 to 40% by weight of an aromatic vinyl-based polymer having a weight average particle diameter of 10 to 150 nm; the (co)polymer (C) is obtained by polymerization of at least one monomer selected from the group consisting of an aromatic vinyl-based monomer, a vinyl cyanide-based monomer, a (meth)acrylic acid ester-based monomer and a maleimide-based monomer.

摘要： Provided is a thermoplastic resin composition having excellent weather resistance, impact resistance, and fluidity and also excellent color developing properties and residence heat stability. A graft copolymer (A) prepared by graft polymerization of a certain amount of a specific monomer (a2)onto a certain amount of composite rubber (a1) composed of a conjugated diene rubber polymer and a cross-linked acrylic ester polymer. The tetrahydrofuran-soluble portion of the composite rubber (a1) has a weight-average molecular weight of 50000 or more in terms of polystyrene and a degree of swelling in toluene of 7.0 or more, or in the composite rubber contained in the graft copolymer, the number of particles having an equivalent-circle diameter of 150 nm or less is 50% or less of the total number of the composite rubber particles.
