PROBLEM TO BE SOLVED: To provide an aromatic polycarbonate with excellent color maintaining molding property.;SOLUTION: The aromatic polycarbonate is obtained by an ester exchange reaction with an intrinsic viscosity [η] of 0.3-1.0 dl/g at 20°C in methylene chloride solvent with a branching parameter G = [η]/[η]lin wherein [η]lin represents a limiting viscosity of a linear polycarbonate having the same weight average molecular weight by light scattering method at 0.15-0.85 and over 0.3 but ≤0.8 mol% of total molar number ratio of a branched structure to one molar unit structure represented by general formula (1), the aromatic polycarbonate composition, the hollow container and the extrusion molded product made of the aromatic polycarbonate composition.;COPYRIGHT: (C)2005,JPO&NCIPI
