Abstract
Disclosed is a thermoplastic resin composition having excellent impact resistance at a low temperature, while maintaining high transparency; this thermoplastic resin composition is obtained by compounding an impact resistance improver into a thermoplastic resin, the impact resistance improver being composed of a graft copolymer which is obtained by polymerizing a vinyl monomer component in the presence of a polymer mixture containing a polymer having butadiene units as an essential component and a polymer having styrene units as an essential component, the polymer mixture containing 45 to 65% by mass of the butadiene units and 35 to 55% by mass of the styrene units.
