PURPOSE: A polycarbonate resin composition is provided to improve the appearance characteristics without deterioration of the mechanical properties by adjusting the apparent density of the pellet to be 0.63-0.65 g/ml. CONSTITUTION: The polycarbonate resin composition comprises 100 parts by weight of a polycarbonate resin; 0.02-0.1 parts by weight of an aliphatic ester compound; and 0.02-0.1 parts by weight of an aliphatic amide compound. Preferably the polycarbonate resin is a linear polycarbonate having a viscosity mean molecular weight of 19,000-25,000; the aliphatic ester compound contains a linear or branched carbon chain of C20-C40; and the aliphatic amide compound contains a linear carbon chain of C20-C40 and is represented by the formula 2, wherein n is an integer of 10-20. More preferably the aliphatic ester compound is represented by the formula 1, wherein n is an integer of 14-18. |
