Disclosed herein are a foamed resin molded body that has excellent impact resistance and rigidity and that is hardly fractured even when subjected to high impact, and a method for manufacturing the same. The foamed resin molded body is made of an olefin-based resin composition containing an olefin resin and a polyamide resin, the olefin-based resin composition has a continuous phase containing the olefin resin and a dispersed phase dispersed in the continuous phase and containing the polyamide resin, and the dispersed phase contains a melt-kneaded product of the polyamide resin and an elastomer having a reactive group that reacts with the polyamide resin.

Films, sheets or profiles useful as optical reflectors may be prepared by extruding a melt-processable acrylic resin composition comprised of acrylic polymer, white pigment and, optionally one or more additives such as impact modifiers, matting agents, UV stabilizers, antioxidants and processing additives onto a layer of ABS, acrylic or other thermoplastic. Alternatively, a monolithic film or sheet or profile useful as an optical reflector is obtained by forming the acrylic resin composition using a melt-processing technique such as extrusion or injection molding without a substrate layer.
