Title (EN) AROMATIC POLYCARBONATE OLIGOMER SOLID
(FR) OLIGOMÈRE DE TYPE POLYCARBONATE AROMATIQUE SOLIDE
(JA) 芳香族ポリカーボネートオリゴマー固形体
Abstract:
(EN) The purpose of the present invention is to provide an aromatic polycarbonate oligomer solid which has a markedly reduced low molecular weight component, has no or markedly reduced chlorine-containing compounds, has a large loose bulk density and is easy to handle. This 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 500-10000, has a low molecular weight component of less than or equal to 5.0 area% in high performance liquid chromatography measurement, and has a loose bulk density of greater than or equal to 0.21 g/cm3.
(FR) La présente invention a pour objet un oligomère de type polycarbonate aromatique solide comprenant un constituant de faible masse moléculaire en quantité nettement réduite, qui ne comprend pas de composés contenant du chlore ou qui comprend des composés contenant du chlore en quantité nettement réduite, qui a une masse volumique apparente non tassée élevée et qui est facile à manipuler. À cet effet, l’invention porte sur un oligomère de type polycarbonate aromatique solide qui comprend un motif répété représenté par la formule générale (1), qui a une masse moléculaire moyenne en poids de 500 à 10 000, qui comprend un constituant de faible masse moléculaire en une quantité, mesurée par chromatographie liquide à haute performance, inférieure ou égale à 5,0 % en surface et qui a une masse volumique apparente non tassée supérieure ou égale à 0,21 g/cm3.
(JA) 低分子量成分が著しく低減され、塩素含有化合物がないか又は著しく低減された、ゆるみ嵩密度が大きく取扱い容易な芳香族ポリカーボネートオリゴマー固形体の提供を課題とする。下記一般式(1) で表される繰り返し単位を含み、重量平均分子量が500~10000、高速液体クロマトグラフィーでの測定において低分子量成分が5.0面積%以下、ゆるみ嵩密度が0.21g/cm以上である芳香族ポリカーボネートオリゴマー固形体により、上記課題は解決できる。
