Abstract: An aromatic polycarbonate oligomer solid contains a repeating unit represented by formula (1) and a repeating unit represented by formula (2), has a weight average molecular weight of 500 to 10,000, 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 0.25 g/cm3. wherein R1, R2, R3, and R4 are independently a hydrogen atom or an alkyl group with 1 to 4 carbon atoms, and R5 and R6 are independently a hydrogen atom or an alkyl group with 1 to 12 carbon atoms. The aromatic polycarbonate oligomer solid has a substantially reduced amount of low-molecular-weight components, no or a substantially reduced amount of chlorine-containing compounds, high loose bulk density, and ease of handling.

Abstract: 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/cm3.
