Foamed and expanded beads including a polyester-basednresin containing at least 35 mole % of an aliphaticnester component. The foamed beads have a gel fraction ofnat least 5 % by weight and comprises at least one gelnaccelerating agent selected from fatty acids having 12-25ncarbon atoms, metal salts of the fatty acids, esters ofnthe fatty acids and amides of the fatty acids in an amountnof 0.15-3 % by weight. A foam molding is obtained bynheating the foamed and expanded beads in a mold. |
