US08218291B2 Monomers for preparing polycarbonate resins, methods of preparing the monomers, polycarbonate resins prepared with the monomers, and capacitors comprising the polycarbonate resins 失效
用于制备聚碳酸酯树脂的单体，制备单体的方法，用单体制备的聚碳酸酯树脂，以及包含聚碳酸酯树脂的电容器

Monomers for preparing polycarbonate resins, methods of preparing the monomers, polycarbonate resins prepared with the monomers, and capacitors comprising the polycarbonate resins
摘要：
A monomer and polycarbonate resin are provided, as are methods of making the monomer. The resin may be used to provide a thin film that has a higher dielectric constant and higher glass transition temperature, and similar breakdown strength and similar dissipation factor to films prepared from polycarbonate resins not so modified. The thin films, in turn, may advantageously be used to form, wholly or in part, articles such as capacitors, sensors, batteries, flexible printed circuit boards, keyboard membranes, motor/transformer insulations, cable wrappings, industrial tapes, interior coverage materials, and the like. In particular, a capacitor comprising the polycarbonate resin is also provided.
摘要（中）：

提供单体和聚碳酸酯树脂，以及制备单体的方法。 该树脂可用于提供具有较高介电常数和较高玻璃化转变温度的薄膜，以及与未进行改性的聚碳酸酯树脂制备的薄膜相似的击穿强度和相似的耗散因数。 薄膜又可有利地用于整体或部分地形成诸如电容器，传感器，电池，柔性印刷电路板，键盘膜，电动机/变压器绝缘体，电缆包装，工业胶带，内部覆盖材料 ，等等。 特别地，还提供了包含聚碳酸酯树脂的电容器。
