Polycarbonate resin composition and molded articles

A polycarbonate-based resin composition, comprising:

• a polycarbonate-based resin (A);
• a perfluoroalkylsulfonimide (B) represented by the following formula (1), and
• an antioxidant (C) comprising at least one antioxidant selected from a phosphorus-based antioxidant and a phenol-based antioxidant,
• wherein a content of the antioxidant (C) is 0.03 part by mass or more and 0.50 part by mass or less with respect to 100 parts by mass of the polycarbonate-based resin (A), the polycarbonate-based resin (A) has a branching ratio of 0.30 mol % or more and 3.0 mol % or less, which is calculated from the expression “(number of moles of structural unit derived from branching agent)/(number of moles of structural unit derived from dihydric phenol+number of moles of structural unit derived from branching agent+number of moles of terminal unit)×100,”
• wherein a content of the perfluoroalkylsulfonimide (B) is 0.05 part by mass or more and 2.0 parts by mass or less with respect to 100 parts by mass of the polycarbonate-based resin (A):
• wherein in the formula (1), R31 represents a perfluoroalkyl group having 1 to 3 carbon atoms, R32 represents a perfluoroalkyl group having 1 to 4 carbon atoms, and M+ represents at least one kind of monovalent cation selected from the group consisting of:
• a lithium ion;
• a sodium ion;
• and a potassium ion, and
• wherein the phosphorus-based antioxidant is selected from the group consisting of triphenyl phosphite, diphenyl nonyl phosphite, diphenyl (2-ethylhexyl) phosphite, tris(2,4-di-tertbutylphenyl) phosphite, tris(nonylphenyl) phosphite, diphenyl isooctyl phosphite, 2,2′-methylenebis(4,6-di-tert-butylphenyl) octyl phosphite, diphenyl isodecyl phosphite, diphenyl mono(tridecyl)phosphite, phenyl diisodecyl phosphite, phenyl di(tridecyl) phosphite, tris(2-ethylhexyl) phosphite, tris(isodecyl) phosphite, tris(tridecyl) phosphite, dibutyl hydrogen phosphite, trilauryl trithiophosphite, tetrakis(2,4-di-tert-butylphenyl)-4,4′-biphenylene diphosphonite, 4,4′-isopropylidenediphenol dodecyl phosphite, 4,4′-isopropylidenediphenol tridecyl phosphite, 4,4′-isopropylidenediphenol tetradecyl phosphite, 4,4′-isopropylidenediphenol pentadecyl phosphite, 4,4′-butylidenebis(3-methyl-6-tert-butylphenyl)ditridecyl phosphite, 1,1,3-tris(2-methyl-4-di-tridecylphosphite-5-tert-butylphenyl)butane, 3,4,5,6-dibenzo-1,2-oxaphosphane, triphenylphosphine, diphenylbutylphosphine, diphenyloctadecylphosphine, tris(p-tolyl)phosphine, tris(p-nonylphenyl)phosphine, tris(naphthyl)phosphine, diphenyl(hydroxymethyl)phosphine, diphenyl(acetoxymethyl)phosphine, diphenyl(β-ethylcarboxyethyl)phosphine, tris(p-chlorophenyl)phosphine, tris(p-fluorophenyl)phosphine, benzyldiphenylphosphine, diphenyl(β-cyanoethyl)phosphine, diphenyl(p-hydroxyphenyl)phosphine, diphenyl(1,4-dihydroxyphenyl)-2-phosphine, and phenylnaphthylbenzylphosphine.
