Polycarbonate resin and molded articles containing the same

Abstract

Provided are a polycarbonate resin which contains structural units (A) to (C) represented by formulae (A) to (C) at a ratio of (A):(B):(C) = 25-45 mol%:25-45 mol%:15-50 mol%, and a molded article which contains this polycarbonate resin.　In the formulae, R1 represents an aliphatic hydrocarbon group having 6 or more carbon atoms; R2 represents a hydrogen atom or a substituent; R3 represents a substituent; n represents an integer of 0 to 8; m represents an integer of (4 + n) or less; R4 represents a hydrogen atom or an aliphatic hydrocarbon group having 1 to 5 carbon atoms; meanwhile, the R1 and R2 moieties, and the R4 moieties do not combine with each other to form a ring; and * denotes a bonding hand.　The 1,4-phenylene group in the formulae may be substituted by an aliphatic hydrocarbon group and / or an aromatic hydrocarbon group.
