A styrene resin is disclosed having excellent moldability and physical properties and is suited for recycling; and a thermoplastic polycarbonate composition with the styrene resin. The styrene resin contains 50 to 90 wt. % of a continuous phase component (S) composed of a copolymer of a styrene monomer, an unsaturated nitrile monomer; and 10 to 50 wt. % of a dispersed phase component on which said monomers have been grafted and which has occluded said copolymer. In the styrene resin, no triple chain unit AAA is detected from the unsaturated nitrite monomer component (A) in the continuous phase component (S) and a double chain unit AA amounts to 3% or less based on the whole units (A) detected.
