Abstract
A resin composition, including: a polycarbonate resin (A) including a constitutional unit represented by formula (1); and a polycarbonate resin (B) including a constitutional unit represented by formula (2), where the polycarbonate resin (A) is a recycled product, and a content of a Br element in the polycarbonate resin (A) is, with respect to 100 parts by mass of the polycarbonate resin (A), 10 ppm by mass or lower. A method for producing the resin composition, including: melt kneading a polycarbonate resin (A) including a constitutional unit represented by formula (1) and a polycarbonate resin (B) including a constitutional unit represented by formula (2).

A resin composition, comprising:
- a polycarbonate resin (A) comprising a constitutional unit represented by formula (1);
- and
- a polycarbonate resin (B) comprising a constitutional unit represented by formula (2),
- wherein the polycarbonate resin (A) is a recycled product, and
- a content of a Br element in the polycarbonate resin (A) is, with respect to 100 parts by mass of the polycarbonate resin (A), 10 ppm by mass or lower:
- wherein in the formula (1),
- X1 represents either one of the following formulae:
- wherein R3 and R4 each independently represent a hydrogen atom or a methyl group, and
- Z represents a group to be bonded with C to form an alicyclic hydrocarbon having 6 to 12 carbon atoms and optionally having a substituent, and
- wherein in the formula (2), R1 represents a methyl group, R2 represents a hydrogen atom or a methyl group, and X2 represents either one of the following formulae:
- wherein R3 and R4 each independently represent a hydrogen atom or a methyl group, and
- Z represents a group to be bonded with C to form an alicyclic hydrocarbon having 6 to 12 carbon atoms and optionally having a substituent.
