摘要： Disclosed herein is a method of producing foamed particles of a polyolefin resin, which are prevented from fusion-bonding among the particles upon their production, and exhibit excellent moldability without impeding fusion bonding property among the foamed particles upon their molding. The method includes dispersing the particles of the polyolefin resin along with a finely particulate silicate mineral as a dispersing agent and at least carbon dioxide as a foaming agent in a dispersion medium in a closed vessel, heating the dispersion to impregnate the resin particles with the foaming agent, and then releasing the resin particles and dispersion medium into an atmosphere of a pressure lower than the internal pressure of the vessel, thereby expanding the resin particles.
