    摘要： A process for producing expanded foam beads from pellets comprising at least one biodegradable polyester. The process comprises (i) producing a suspension comprising pellets in an aqueous suspension medium, (ii) impregnating the pellets present in the suspension from step (i) with at least one physical blowing agent by heating the pellet suspension to a depressurization temperature IMT, with stirring, to provide pellets laden with blowing agent in the suspension medium, and (iii) depressurizing the suspension obtained in step (ii) and cooling the depressurized suspension with a liquid aqueous coolant, in order to obtain the expanded foam beads. The blowing agent can be added in step I, or in step ii during the heating phase or following the heating phase. Following the heating phase, the suspension is maintained at a temperature in the range from IMT minus 5° C. to IMT plus 2° C. for 3 to 100 minutes, and the ratio of aqueous coolant to suspension medium is at least 0.3. The invention further relates to expanded foam beads obtained by the process and to moldings that are produced from the expanded foam beads.

    摘要： Polyethylene-based resin foamed particles are obtained having good productivity, achieve an increase in foaming ratio, and in which a miniaturization of the average cell diameter is suppressed. A polyethylene-based resin in-mold-foam-molded body using the foamed particles is reduced in yellowing of the surface of the molded body and has favorable surface beauty (surface smoothness). The foamed particles contain, as a base resin, a polyethylene-based resin composition containing 1000 ppm or more and 4000 ppm or less in total of one or more compounds selected from the group consisting of antioxidants, metal stearates, and inorganic substances and 50 ppm or more and 20000 ppm or less of hydrophilic compounds, in which the Z average molecular weight is 30×104 or more and 100×104 or less, the surface layer film thickness is 11 μm or more and 120 μm or less, and the open-cell ratio is 12% or less.

    摘要： Decorative foamed articles are prepared from foamed pellets, beads, particles, or other articles of a thermoplastic elastomer infused with a supercritical fluid in a pressurized container, then rapidly depressurized and heated either by immersion in a heated fluid that can rapidly heat the article or with infrared or microwave radiation to heat and foam the pellets, beads, particles, or other articles that are then molded into the articles. The pellets are dyed with a nonionic or anionic dye one of: (1) before being infused with the supercritical fluid, (2) during being infused with the supercritical fluid by a nonionic or anionic dye dissolved or dispersed in the supercritical fluid, which optionally comprises a polar liquid, (3) during immersion in the heated fluid, where the heated fluid contains the dye, or (4) after being foamed.
