Abstract

The object of this invention is to provide a resin composition that contains a polymer obtained from biomass resources and constitutes molded articles excellent in heat resistance, mechanical properties and durable stability, this invention including a resin composition comprising (i) a resin component containing 95 to 5% by weight of an aromatic polycarbonate (component A) and 5 to 95% by weight of polylactic acid (component B), (ii) 0.001 to 10 parts by weight, per 100 parts by weight of the resin component, of a phosphoric ester metal salt (component C), and (iii) 0.01 to 5 parts by weight, per 100 parts by weight of the polylactic acid (component B), of a terminal blocker (component F), the stereo-complex crystal content (X) of the following expression (I) being 80% or more, X (%)={.DELTA.Hb/(.DELTA.Ha+.DELTA.Hb)}.times.100 (I) wherein .DELTA.Ha and .DELTA.Hb are a melting enthalpy (.DELTA.Ha) of a crystal melting point that appears at lower than 190.degree. C. and a melting enthalpy (.DELTA.Hb) of a crystal melting point that appears at 190.degree. C. or higher but less than 250.degree. C., respectively, in a temperature-elevation process by a differential scanning calorimeter (DSC), and molded articles thereof.
