    • The present disclosure relates to a degradable material comprising (a) from about 60 weight percent to about 97 weight percent of a first material based on the total weight of the degradable material, and (b) from about 3 weight percent to about 40 weight percent of a second material based on the total weight of the degradable material, where the second material is an oligomer comprising lactate and giycolate. In another aspect, the present disclosure provides a degradable material comprising (a) poly lactic acid, and (b) an oligomer comprising lactate and giycolate, wherein the degradable material has a Tg less than 56°C. In still another aspect, the present disclosure provides a degradable material comprising (a) poly lactic acid, and (b) an oligomer comprising lactate and giycolate, wherein the degradable material has a tan delta peak of less than 65°C. It has been surprisingly found that the degradable materials according to the present disclosure provide physical properties that are not inherent to poly lactic acid alone. It has also been surprisingly found that the degradable materials disclosed herein provide improvements with respect to the processability, production costs, flexibility and ductility without decreasing their degradability.
    • 本公开内容涉及可降解材料,其包含(a)基于可降解材料的总重量的约60重量%至约97重量%的第一材料,和(b)约3重量%至约40重量% 基于可降解材料的总重量的第二种材料,其中第二种材料是包含乳酸盐和双羟萘酸盐的低聚物。 在另一方面,本公开提供了一种可降解材料,其包含(a)聚乳酸和(b)包含乳酸盐和木糖苷的低聚物,其中所述可降解材料的Tg小于56℃。 在另一方面,本公开提供了一种可降解材料,其包含(a)聚乳酸和(b)包含乳酸盐和木糖苷的低聚物,其中所述可降解材料具有小于65℃的tanδ峰。 令人惊奇地发现,根据本公开的可降解材料提供了单独聚乳酸不固有的物理性质。 还惊奇地发现,本文公开的可降解材料提供了相对于可加工性,生产成本,柔韧性和延展性而不降低其降解性的改进。

    • A method for forming a polylactide film includes the steps (a) through (c). In step (a), a treated tool surface is provided with a release coating. The treated tool surface is maintained at a predetermined temperature of about the glass transition temperature of the polylactide or higher. In step (b) the treated tool surface is contacted with a molten polylactide composition to provide a polylactide film. The film is at least partially crystalline, and the crystallinity of the polylactide film is enhanced due to exposure of the molten polylactide composition to the treated tool surface at the predetermined temperature. In step (c) the polylactide film is removed from the treated tool surface. Additionally, a film is provided that is made by the foregoing method, and the film may be formed into an article or a part of an article. In some cases, the article is a disposable garment such as a diaper. In other cases, the article may be a tape made with the foregoing film, where the film includes first and second major surfaces and a layer of adhesive on at least one of the major surfaces.
    • 形成聚丙交酯膜的方法包括步骤(a)至(c)。 在步骤(a)中,经处理的工具表面设置有剥离涂层。 经处理的工具表面保持在约聚丙交酯的玻璃化转变温度或更高的预定温度。 在步骤(b)中,将经处理的工具表面与熔融的聚丙交酯组合物接触以提供聚丙交酯膜。 膜至少部分结晶,并且由于在预定温度下将熔融的聚丙交酯组合物暴露于经处理的工具表面,聚丙交酯膜的结晶度得到增强。 在步骤(c)中,从经处理的工具表面除去聚丙交酯膜。 另外,通过上述方法制成薄膜,并且薄膜可以形成制品或制品的一部分。 在一些情况下,该物品是诸如尿布的一次性衣物。 在其他情况下,制品可以是用上述膜制成的带,其中膜包括第一和第二主表面以及至少一个主表面上的粘合剂层。
