摘要： The present invention provides a composition comprising polycarbonate wherein the polycarbonate has a very low Fries content (e.g., above 5 ppm and below 360 ppm). The present invention also provides a polycarbonate having a very low Fries content which is made by the melt process. This polycarbonate has high ductility and high impact strength. The invention also provides a method for making these compositions. Another aspect of the invention is an optical disk comprising polycarbonate having a very low Fries content which is made by the melt process. Such optical disks resist breakage due to bending.

摘要： Increasing the endcap level to a level greater than about 90% for Optical Quality (OQ) Melt Polycarbonate significantly reduces the as-molded static charge for injection molded parts for Optical Disc applications. The use of resins with higher endcap levels in combination with antistatic additives provides a highly robust formulation suitable for even the most demanding emerging formats as Digital Versatile Disc (DVD) and in all commercial Optical media molding machines. Thus, optical quality polycarbonates are prepared by performing a base-catalyzed polymerization of a diaryl carbonate and a dihydric phenol under conditions effective to produce a polycarbonate product having an endcap level of 90% or greater.
摘要翻译：将端盖水平提高到光学质量（OQ）的大约90％以上熔融聚碳酸酯显着降低了用于光盘应用的注塑部件的模制静电荷。使用具有更高端帽水平的树脂与抗静电添加剂相结合提供了高度鲁棒的配方，适用于甚至最苛刻的新兴格式，如数字多功能光盘（DVD）和所有商业光学介质成型机。因此，通过在有效地制备端帽水平为90％以上的聚碳酸酯制品的条件下进行碳酸二芳基酯和二元酚的碱催化聚合来制备光学质量的聚碳酸酯。
