ABSTRACT:
The object of the present invention is to provide a polycarbonate resin composition which has excellent transparency and durability against molding heat, which gives a molded article having an excellent mold release property, reduced strains, improved cracking resistance and, preferably, weatherability, and which is particularly suitable for a transparent member for a vehicle, pellets thereof and a molded article thereof, and the present invention provides a polycarbonate resin composition obtained by blending 100 parts by weight of a polycarbonate resin (Component A) and 0.005 to 2 parts by weight of a full ester (Component B) 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 4 to 20, pellets thereof and a molded article thereof.
