Abstract
The purpose of the present invention is to provide an aromatic polycarbonate oligomer solid which has a markedly reduced amount of a low molecular weight component, has no or a markedly reduced amount of chlorine-containing compounds, has a high loose bulk density and is easy to handle. The purpose is met by an aromatic polycarbonate oligomer solid which includes a repeating unit represented by general formula (1), has a weight average molecular weight of 500 to 10000, has a low molecular weight component of less than or equal to 5.0 area % as measured by high performance liquid chromatography, and has a loose bulk density of greater than or equal to 0.20 g/cm3.
Claims2
An aromatic polycarbonate oligomer solid comprising a repeating unit represented by the following general formula (1):
- (wherein R1 and R2 each independently represent a hydrogen atom or a methyl group) and having a weight average molecular weight of 500 to 10000, a low molecular weight component of 5.0 area % or less as measured by high performance liquid chromatography, and a loose bulk density of 0.20 g/cm3 or more.
An aromatic polycarbonate oligomer solid comprising an aromatic dihydroxy compound represented by the following general formula (2):
- (wherein R1 and R2 each independently represent a hydrogen atom or a methyl group) and a carbonic acid diester and having a weight average molecular weight of 500 to 10000, a low molecular weight component of 5.0 area % or less as measured by high performance liquid chromatography, and a loose bulk density of 0.20 g/cm3 or more.
