摘要

A process for producing a foamed blow-molded article, including melting and mixing a branched polycarbonate resin having a specific polystyrene equivalent weight average molecular weight, a specific weight average absolute molecular weight and a relatively high terminal hydroxyl group content, a linear polycarbonate resin having specific polystyrene equivalent weight average molecular weight, a specific weight average absolute molecular weight and a relatively low terminal hydroxyl group content and a branching agent to obtain a polycarbonate resin “A”, mixing the polycarbonate resin “A” with a blowing agent to obtain a foamable molten resin composition, extruding the foamable molten resin composition to obtain a foamed parison, and blow-molding the foamed parison.
