PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin molded object capable of obtaining a molding material excellent in mechanical physical properties such as tensile elastic modulus, impact strength or the like by dispersing a polyester resin being a general-purpose resin not taking a liquid crystal structure in a molten state in a thermoplastic resin in a high molecularly oriented state. SOLUTION: A process for heating a resin mixture comprising a thermoplastic resin and a thermoplastic polyester resin having a melting point higher than the moldable temperature of the thermoplastic resin to a temperature not lower than the melting point of the polyester resin and extruding the molten resin mixture while stretching the same and a process for stretching the mixture extruded in a molten state in the extrusion direction at a temperature higher than the glass transition temperature of the polyester resin and lower than the low temperature crystallizing temperature thereof. |
