Optical polycarbonate and applications thereof |
| abstract |
This specification describes an optical polycarbonate composition obtained by the melt polycondensation of a bisphenol and a carbonic diester in the presence of an alkaline compound catalyst, wherein said optical polycarbonate composition comprises (i) a compound expressed by the following Formula (A) in an amount of 30 to 2000 ppm; (ii) a compound expressed by the following Formula (B) in an amount of 30 to 4000 ppm; and (iii) a compound expressed by the following Formula (C) in an amount of 80 to 8000 ppm. The polycarbonate composition has a viscosity average molecular weight of between 12,000 and 18,000 and the portion with a molecular weight (as measured by GPC) of 1000 or less accounts for 0.5 to 1.5 wt%. |
