Method for producing polycarbonate resin, and molded body

A method for producing a polycarbonate resin containing a structural unit derived from an aromatic dihydroxy compound represented by Formula (1-a) below, the method comprising

• polymerizing the aromatic dihydroxy compound represented by Formula (1-a),
• wherein a raw material substance, in which a concentration of a compound represented by Formula (2-a) below as impurities, is 80 ppm or less relative to the total weight of the aromatic dihydroxy compound represented by Formula (1-a) and the compound represented by Formula (2-a), is used during the polymerization:
• in Formula (1-a),
• R1 and R2 each independently represent a hydrogen atom, a halogen atom, an optionally substituted and optionally branched C1-C20 alkyl group, or an optionally substituted C6-C30 aryl group, and
• X represents an optionally branched C1-C20 alkyl group, C1-C20 alkynyl group, C1-C20 alkenyl group or C6-C30 aryl group, which may be substituted with a halogen atom,
• in Formula (2-a),
• R1 and R2 each independently represent a hydrogen atom, a halogen atom, an optionally substituted and optionally branched C1-C20 alkyl group, or an optionally substituted C6-C30 aryl group,
• X represents an optionally branched C1-C20 alkyl group, C1-C20 alkynyl group, C1-C20 alkenyl group or C6-C30 aryl group, which may be substituted with a halogen atom,
• a and b each independently represent an integer of 0-3, provided that not both of a and b are 0, and
• provided that the sum of (a+m) is an integer of 4 or less, and the sum of (b+n) is an integer of 4 or less, and
• wherein a 5 cm solution of a 7 mass % dichloromethane solution of the polycarbonate resin has a b* value of 2.3 or less wherein, during the polymerization, the aromatic dihydroxy compound represented by Formula (1-a) is polymerized by an interfacial polycondensation process.
