Patent ID: 7241825

Claim:
A polycarbonate resin composition obtained by blending 100 parts by weight of a polycarbonate resin (Component A) having a viscosity average molecular weight of 18,000 to 25,000 and 0.005 to 2 parts by weight of an ester (Component B) having an esterification rate of 85% or more, from an aliphatic polyhydric alcohol having 4 to 8 hydroxyl groups and 5 to 30 carbon atoms and an aliphatic carboxylic acid having 10 to 22 carbon atoms, said Component B having a 5% weight loss temperature, measured by TGA (thermogravimetric analysis), of 250 to 360° C. and having an acid value of 5 to 20, and wherein the aliphatic carboxylic acid of said Component B contains a palmitic acid component and a stearic acid component, and in a peak area by a gas chromatography mass spectrometry method (GC/MS method) thereof, the total of a palmitic acid component area (Sp) and a stearic acid component area (Ss) is at least 80% of the entire aliphatic carboxylic acid component area, and the area ratio (Ss/Sp) is 1.3 to 30.
