Embodiment

[0187] Hereinafter, the present invention will be described more specifically by way of examples. The present invention is not limited to the following examples.

[0188] In the following raw materials used, Examples, and Comparative Examples, unless otherwise stated, parts and % are based on mass.

[0189] The content of component (A), component (B), component (C), component (D), and component (A) containing a structural unit (GMA unit) based on an α,β-unsaturated glycidyl ester compound is based on the component ( Content when the total of A), component (B), and (C) component is 100%.

[0190] In Tables 1 to 3 described later, the ratio of the ultrahigh molecular weight component (Q2) to the chloroform-soluble component (Q) of the vinyl resin in the thermoplastic resin composition is described as "ultrahigh molecular weight component (Q2 )Proportion".

Abstract

Provided is a thermoplastic resin composition whereby a molded article having a non-speckle and excellent matting appearance can be obtained. A thermoplastic resin composition comprising a vinyl graft polymer (A), a vinyl non-graft polymer (B), and a matting agent (C), characterized in that: in the chloroform-soluble component (Q) in the thermoplastic resin composition, the content of the chloroform-soluble component (Q) is less than the content of the chloroform-soluble component (Q), and the content of the chloroform-soluble component (Q) is less than the content of the chloroform-soluble component (Q). The mass ratio (Q1) / (Q2) of the vinyl resin component (Q1) having a weight-average molecular weight of less than 1,000,000 to the vinyl resin component (Q2) having a weight-average molecular weight of 1,000,000 or more is in the range of 99.5 / 0.5 to 55 / 45.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition and a molded article from which a molded article having an appearance free from spots and excellent in matting properties can be obtained, and a molded article thereof. Background technique [0002] ABS resin is widely used in automobiles, home appliances, office equipment (OA) and other fields because of its excellent mechanical properties, heat resistance, and formability. [0003] When parts made of ABS resin are used in automobile interiors, for example, the driver may be dazzled by the sunlight reflected from the surface of the molded product, or the instrument may become difficult to see due to the reflected light around the instrument. Therefore, an appearance excellent in matting property is required from the viewpoint of safety. [0004] Housings and chassis of home appliances, office equipment, and the like are required to have an appearance excellent in matting properties fr...
