摘要： The purpose of the present invention is to provide an aromatic polycarbonate oligomer solid with substantially reduced low-molecular-weight components, no or a substantially reduced amount of chlorine-containing compounds, high loose bulk density, and ease of handling. The aromatic polycarbonate oligomer solid contains a repeating unit represented by general formula (1), has a weight average molecular weight of 500 to 10000, low-molecular-weight components less than or equal to 5.0 area% measured with high-speed liquid chromatography, and a loose bulk density of greater than or equal to 0.30 g/cm 3 .
