摘要： A thermoplastic composition is described, based on a copolycarbonate which includes at least two structural units. Structure I is usually a conventional carbonate based on bisphenol A, while structure II is a bisphenol carbonate which includes branched or linear groups extending from a bridging carbon atom or carbon group which connects two aromatic rings. The compositions exhibit very good melt flow, along with enhanced shear-thinning behavior. These characteristics are important for optical disc applications. Thus, related articles are described, along with processes for preparing such articles.
摘要翻译：基于包含至少两个结构单元的共聚碳酸酯描述热塑性组合物。结构I通常是基于双酚A的常规碳酸酯，而结构II是双酚碳酸酯，其包括从连接两个芳环的桥连碳原子或碳基延伸的支链或直链基团。组合物显示非常好的熔体流动，以及增强的剪切稀化行为。这些特性对于光盘应用很重要。因此，描述了相关的文章以及制备这些物品的过程。
