摘要： A biodisintegrable thermoplastic resin foam and a process for producing same are disclosed, the biodisintegrable thermoplastic resin foam being comprised as a substrate thereof a mixed resin comprising 5-40 weight % of a thermoplastic resin decomposable by microorganisms and 95-60 weight % of a thermoplastic resin not decomposable by microorganisms and being characterized in that the individual aerial cells constituting the foam have an average cell wall thickness of 1-100 µm and an apparent density of 0.5 g/cm³ or less than 0.5 g/cm³. The biodisintegrable thermoplastic resin foam is easily disintegrable after disposal in an environment where microorganisms exist so that it can be reduced in bulkness and gives no harmful effect on the life of natural plants and animals. The foam incorporated with a filler can be promoted in disintegration by microorganisms. Thus the present invention affords an effective means for solving various problems in the treatment of disposed materials.
摘要翻译：公开了一种生物可分解热塑性树脂发泡体及其制造方法，该生物可分解热塑性树脂发泡体作为其基材包含5-40重量％的由微生物分解的热塑性树脂和95-60重量％热塑性塑料的混合树脂微生物不能分解的树脂，其特征在于，构成泡沫的各个空气电池的平均泡孔壁厚度为1-100μm，表观密度为0.5g / cm 3或小于0.5g / cm 3 >。生物可分解的热塑性树脂发泡体在微生物存在的环境中处理后容易崩解，从而可以降低体积，并且对天然植物和动物的寿命没有不利影响。掺入填料的泡沫可以通过微生物分解来促进。因此，本发明提供了解决处理材料的各种问题的有效手段。

摘要： A biodegradable plastic composition, which may be in the form of a molded body, includes gelatinized starch and a biodegradable, aliphatic polyester resin having a melting point of 45-130 °C. The plastic is produced by kneading a blend containing a starchy substance selected from non-gelatinized, granular starch and gelatinized starch and the aliphatic polyester resin at a temperature higher than the melting point of the aliphatic polyester in the presence of water in an amount of 1-45 % based on the weight of the starchy substance.
