    摘要: Provided is a polycarbonate resin composition comprising: a polycarbonate resin comprising a constituent unit having an alicyclic hydrocarbon site where a carbonate group is linked to two carbon atoms that constitute a ring and are adjacent to each other; and one or two or more compounds selected from the group consisting of a compound having an amide bond, a sulfur compound, and a phosphite ester compound, wherein weight-average molecular weight Mw of the polycarbonate resin measured by size-exclusion chromatography using polystyrene as a standard sample is 50,000 or larger and 500,000 or smaller.

    摘要: A thermoplastic resin composition for foam molding including:
    a component (A), listed below, in an amount of 1 to 20 parts by mass;
    a component (B), listed below, in an amount of 0 to 50 parts by mass;
    a component (C), listed below, in an amount of 40 to 90 parts by mass; and
    a high-molecular-weight resin (D) that is different from the components (A) to (C) and has a weight average molecular weight greater than or equal to 2,000,000, wherein when a total of the components (A) to (C) is 100 parts by mass, an amount of the high-molecular-weight resin (D) is 0.1 to 10 parts by mass:
    component (A): a rubber-reinforced styrenic resin (A) derived from polymerization, in the presence of a rubbery polymer (a), of a vinyl monomer (b1), the vinyl monomer (b1) including an aromatic vinyl compound;
    component (B): a styrenic resin (B) derived from polymerization a vinyl monomer (b2), the vinyl monomer (b2) including an aromatic vinyl compound; and
    component (C): an aromatic polycarbonate resin (C).
