Claim:
1. A transparent thermoplastic molding composition consisting of: one or more polycarbonates resins; a transparent polyester resin selected from the group consisting of poly(cyclohexanedimethanol terephthalate), poly(cyclohexanedimethanol-co-ethylene terephthalate), glycol-modified polyethylene terephthalate, poly(1,4-cyclohexanedimethyl-1,4-cyclohexanedicarboxylate) and mixtures therof; from about 0.005 weight percent to about 2 weight percent, based on the weight of the composition, of a perfluoroalkylsulfonic acid salt of the formula (I):  wherein R denotes perfluorinated linear or branched carbon chain having 1 to 30 carbon atoms, A denotes a direct bond or an aromatic nucleus, n denotes an integer of 1 or 2, and X denotes a metal element selected from the first or the second column in the Periodic Table of the Elements; and from about 0 weight percent to about 5 weight percent, based on the weight of the composition, of a glycerol monostearate (GMS), wherein the transparent thermoplastic molding composition has a total transmittance according to ASTM D-1003 of greater than about 84% and an electric resistivity according to ASTM D-257 (at 277° C. after 1000 seconds electrification at 100 volts) of less than about 2.5E+06 ohm-m.
