A polycarbonate composition comprising (A) 100 parts by weight of a polycarbonate resin and (B) 1 to 80 parts by weight of an isoprene-base graft copolymer, wherein; said isoprene-base graft copolymer (B) is prepared by polymerizing(a) 20 to 100 parts by weight of one or more vinyl monomers selected from the group consisting of acrylic esters, methacrylic esters, aromatic monovinyl compounds, and cyanovinyl compounds, and(b) 0 to 5 parts by weight of a polyfunctional vinyl monomer in the presence of(c) 100 parts by weight of a copolymer having an isoprene content of 5 to 100% by weight and an acrylic ester content of 0 to 95% by weighthas excellent thermal stability, low temperature impact resistance, jet-black colorability, and solvent resistance. Such a polycarbonate composition is suitable as a material for moldings in the fields of automobiles, home electric appliances, etc.
