Patent ID: 7956126

Claim:
A melt blended styrene-based resin composition comprising (A) a styrene-based resin, (B) a thermoplastic resin other than styrene-based resins, (c1) a modified styrene-based polymer containing vinyl-based monomer units respectively containing at least one kind of a functional group selected from the group consisting of an epoxy group and an oxazoline group, and (c2) a polycarbonate-based graft polymer, wherein the styrene-based resin (A) and the thermoplastic resin other than styrene-based resins (B) have a co-continuous structure with a wavelength of concentration fluctuation of 0.001 to 1 μm or a dispersed structure with a distance between particles of 0.001 to 1 μm, wherein the melt blended styrene-based resin composition is formed via melt blending at a resin pressure kept at 2.0 MPa to 5.0 MPa at least at one or more places in the melt blending space or temporarily during the melt blending period of time.
