Abstract: The present invention provides a method for producing polylactic acid-based resin foamed particles for in-mold foam-molding from which a polylactic acid-based resin foam-molded article excellent in heat resistance and mechanical strength can be obtained by in-mold foam-molding. In the method of the present invention for producing polylactic acid-based resin foamed particles for in-mold foam-molding, a rotary blade is rotated at a given rotation speed while being always in contact with the front end surface of a nozzle and a polylactic acid-based resin extrudate extrusion-foamed through a nozzle is cut with the rotary blade, so that it is possible to cut the polylactic acid-based resin extrudate surely to obtain substantially spherical polylactic acid-based resin foamed particles. Therefore, when polylactic acid-based resin foamed particles are used for in-mold foam-molding, the polylactic acid-based resin foamed particles foam uniformly in all directions and, as a result, the foamed particles are thermal fusin bonded to unite together strongly in all direction.

Abstract: Polyamide pre-expanded particles of this disclosure have a peak temperature of a maximum endothermic peak of 150-275° C. on a DSC curve obtained while being heated from 30° C. to 280° C. at a heating rate of 10° C./min using a DSC. The width of the peak is 30-80° C. when a straight line approximating the DSC curve on a high-temperature side relative to the peak after an end of melting is used as a baseline. The width corresponds to a difference between an extrapolated melting start temperature which is a temperature at an intersection point between a tangent line at an inflection point of the peak on a low-temperature side and the baseline, and an extrapolated melting end temperature which is a temperature at an intersection point between a tangent line at an inflection point of the peak on a high-temperature side and the baseline.
