Optical polycarbonate compositions |
| abstract |
An optical polycarbonate composition is obtained by :nformulatingn [C-1] a sulfonic acid compound having a pKa value of 3nor less and/or a derivative formed from said compoundnin an amount of 0.00001-0.0005 part by weight nper 100 parts by weight of [A] a polycarbonate resin having an intrinsic viscositynof 0.30-0.65 dL/g, as measured in 20° C methylenenchloride, nand containing also: [D] a phosphorus compound in an amount of 0.1 part bynweight or less, and/or [E] an epoxy compound in an amount of 0.001-0.1 part bynweight. |
