Patent number: 6262218Abstract: 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.Type: GrantFiled: November 29, 1999Date of Patent: July 17, 2001Assignee: General Electric CompanyInventors: Kazushige Inoue, Hiromi Ishida, Tomoaki Shimoda, Theodorus L.
