Title: GLASS FILLER-CONTAINING POLYCARBONATE RESIN COMPOSITION, AND MOLDED BODY THEREOF
Abstract:
The present invention pertains to a polycarbonate resin composition containing: an aliphatic polycarbonate resin (A) having a specific repeating unit; and a glass filler (B) having a specific composition and containing 5 mass% or less total of Li2O, Na2O, K2O and Cs2O, wherein the refractive index of the aliphatic polycarbonate resin (A) is 1.480-1.520 with respect to light having a wavelength of 589.3 nm, the refractive index of the glass filler (B) is 1.485-1.520 with respect to light having a wavelength of 589.3 nm, and the difference in refractive index between the aliphatic polycarbonate resin (A) and the glass filler (B) is at most 0.003 with respect to light having a wavelength of 486.1 nm, at most 0.001 with respect to light having a wavelength of 589.3 nm, and at most 0.001 with respect to light having a wavelength of 656.3 nm. Provided are: a polycarbonate resin composition capable of providing a molded body having excellent transparency; and a molded body having excellent transparency.
