The present invention provides certain sulfonated copolyetherester compositions containing hydroxyalkanoic acids and processes for producing such sulfonated aromatic copolyetheresters. The invention further provides shaped articles, preferably in the shape of films, coatings and laminates, having improved thermal properties, wherein the shaped articles are produced from the certain sulfonated copolyetherester compositions. Some of these materials are also biocompostable. The sulfonated copolyetheresters are produced from a mixture of an aromatic dicarboxylic acid component, hydroxyalkanoic acid component, a sulfonate component, a poly(alkylene ether) glycol component, a glycol component, an optional other glycol component, an optional branching agent, and an optional color reducing agent.
本发明提供了某些含有羟基烷酸的磺化共聚醚酯组合物和生产这种磺化芳香族共聚醚酯的工艺。本发明进一步提供了具有更好热性能的定型物品,最好是薄膜、涂层和层压板形状的物品,其中定型物品是由某些磺化共聚醚酯组合物生产的。其中一些材料还可进行生物堆肥。磺化共聚醚酯由芳香族二羧酸组分、羟基烷酸组分、磺酸盐组分、聚(烷基醚)乙二醇组分、乙二醇组分、任选的其他乙二醇组分、任选的支化剂和任选的减色剂的混合物制成。
