(57) [Abstract] [Problem] To provide a foam having excellent mechanical strength and heat resistance, which can be recycled even after use, and which can perform clean and effective decomposition such as natural decomposition and compost decomposition. Provide without. SOLUTION: The aliphatic polyester (A) and (meth) What is claimed is: 1. A biodegradable polyester resin foam comprising an acrylic ester (B1) and / or glycidyl ether (B2), wherein the foam contains 0.2% by mass or more of lactide. Aliphatic polyester (A), (Meth) acrylic acid ester (B1) and / or glycidyl ether (B2), and an organic peroxide (C) are melt-kneaded and foamed simultaneously with a crosslinking reaction in the presence of lactide. A method for producing a degradable polyester resin foam. |
