Articles, including films, coatings and laminates, are produced from certain sulfonated aliphatic-aromatic polyetherester compositions, which have an optimized combination of fast biodegradation rates and enhanced thermal properties when compared to the sulfonated aliphatic-aromatic polyetherester compositions of the art. The articles may be further processed to form useful shaped articles, such as sheets, thermoformed containers, and coatings that can be applied to, for example, films or other substrates. The disclosed polyetheresters are based on copolyesters produced from a mixture containing aromatic dicarboxylic acids, aliphatic dicarboxylic acids, poly(alkylene ether) glycols, glycols, and components containing alkali metal or alkaline earth metal sulfo groups.
由某些磺化脂肪芳香族聚醚酯组合物制成的物品,包括薄膜、涂层和层压板,与现有技术中的磺化脂肪芳香族聚醚酯组合物相比,具有快速生物降解率和增强热性能的优化组合。这些物品可进一步加工成有用的成型物品,如板材、热成型容器和可应用于薄膜或其他基材等的涂层。所公开的聚醚酯以共聚多酯为基础,共聚多酯由含有芳香族二羧酸、脂肪族二羧酸、聚(亚烷基醚)乙二醇、乙二醇和含有碱金属或碱土金属磺基的组分的混合物制得。
